In order to ensure the safety of passengers and on-board personnel, finite element calculation is used at SNCF as part of the acquisition, renovation / modernization projects of trains as a decision aid and preparation for testing approval of trains. This is the main case of the mechanical strength of bolted and screwed assemblies, and more and more of the integration of composite materials into rolling stock structures in order to make them more capacious and less energy intensive. To do this, SNCF is developing methodologies to make the modeling of bolted assemblies and composite parts more reliable, as well as topology optimization. The tools of the HyperWorks suite, and in particular, the OptiStruct solver, allow SNCF to represent its types of materials, as well as these phenomena (bolted assemblies + topology optimization).

This presentation is by Program Manager Rob Jopson. It’s a given that the simulation models we build are intended to capture and predict physical behavior, the data used to create them is not always representative of the manufacturing process used to build the physical part. For layered composite parts in particular, this mismatch can cause significant overhead in managing the simulation data as the model is created and evolves. To solve this problem, Altair’s ply-based modeling methodology strives to maintain a 1:1 relationship between the simulation data and the manufacturing process, independent of solver. The latest developments of this methodology will be presented as a workflow in the new Composite Browser, available in HyperWorks. The recording is about 18 minutes long and was originally presented at the 2020 ATCx Composites.

Variational asymptotic beam section (VABS) is a unique technology continuously funded by the US Army since 1988 and it has become a tool of choice in the helicopter and wind turbine industries for modeling composite rotor blades. With analysis of a finite element meshed cross section, VABS can compute the best set of beam properties for 1D beam analysis and also accurately recover 3D stress/strain distribution over the cross section. VABS has been integrated with HyperWorks and OptiStruct for Altair users to take advantage of this powerful technology for better design and analysis of composite beam-like structures.  The recording of the presentation by Dr. Wenbin Yu, CTO of AnalySwift, is almost 20 minutes long, and was originally presented at the 2020 ATCx Composites.

This presentation is by Markku Palanterä, Director Composites Business Development, Altair The composites design and simulation suite by Altair is actively developed with a holistic view to cover all stages of the process from material modeling all the way to the certification of composite structures. On the material modeling side, the focus is on continuous further development of Altair’s multiscale modeling technology for continuous fiber composites and injection molded plastics, but not forgetting further application areas, such as additive manufacturing. The ply-based composite modeling in Altair HyperWorks has recently undergone a major update to achieve an improved, more efficient modeling workflow. This together with planned further developments tie the modeling even better with the manufacturing to create realistic models of composite components as built. Altair’s solver technology for implicit and explicit analyses can utilize multiscale material models to accurately describe composite material nonlinear behavior up to failure. Altair’s unique composites optimization technology is being enhanced with the repeat laminate concept that provides added efficiency and user control over lay-up design. To further complement the idea of an integrated system with all the necessary composites capabilities, the Composite Stress Toolbox has been introduced in HyperWorks to support design and certification. The recording is about 22 minutes long and was originally presented at the 2020 ATCx Composites.

The recording is about 41 minutes long and was originally presented at the 2020 ATCx Composites.

This presentation is by André Mönicke, Program Manager Classical composite analysis and certification methods continue to be used in a significant share of the composite design process. In particular, applying classical methods early in design, and integrating them with finite methods as soon as possible can allow faster decisions which will be rewarded when it comes time for certification. Altair’s latest developments to respond to those needs will be presented, covering the Integrated Composite Stress Toolbox and a Certification framework available in HyperWorks. The recording is about 20 minutes long and was originally presented at the 2020 ATCx Composites.

The recording is about 28 minutes long and was originally presented at the 2020 ATCx Composites.

This presentation is by Dr. Tomasz Garstka and Graham Barnes, LMAT Ltd. Manufacturing induced deformations and residual stresses are an unavoidable consequence of processing composites at elevated temperatures. A number of mechanisms have been identified causing residual stresses and distortions, including mismatch in the thermal expansion, cure shrinkage of the resin, consolidation and tool-part interaction. These mechanisms usually act collectively through the curing process and may lead to severe changes in the laminate characteristic. When cured and exposed to natural environment moisture swelling, as well as subsequent stress relaxation mechanisms lead to further geometrical changes. A novel cure simulation solver is demonstrated here with the application to typical aircraft components. The recording is about 10 minutes long and was originally presented at the 2020 ATCx Composites.

Dr. Royston Jones, Global CTO, Altair Consultancy, discusses how the global pandemic has been a catalyst for companies to harness the potential of simulation by reconfiguring their established design processes and traditional organizational structures. Technologies and methods that can deliver design feedback at the speed of development are already available; reducing expensive physical testing while injecting innovation into a company’s product. The rapid evolution towards a connected everything is having a huge effect on design. From autonomous and electric mobility to smart consumer products with new business models, development teams must now integrate simulations of controls systems into complex multi-physics models enriched by data captured by sensors in the field. Especially during concept development when rapid exploration of design ideas is essential, a full embrace of simulation will be essential to compete. The recording is about 19 minutes long, and was presented at the 2020 Global Altair Technology conference.

Dr Venkat Perumal, Senior Principle Engineer at Stryker Global Technology Center discusses the adoption of simulation in Medical Device industry and how it helps shorten the overall product development cycle time & cost.

Using remote visualization tools on our HPC cluster has allowed PING to reach design convergence much faster on all types of golf clubs. Due to the speed of the simulations and the addition of display manager, the design team can make modifications and iterate on their files within the same day.

Presentation by Konstantin Arhiptsov & by Eitan Maler, Simulation Dept. IWI Israel Weapon Industries (IWI) at the ATCx in Israel, Netanya on October 30, 2019. These days, in IWI, complete multi physics simulation is an integrated tool in the development of any new product. The motivation is to completely simulate one or two firing cycles as close to reality. First step is the Multi Body Dynamics simulation to check all mechanism are synchronized and work properly. Second is the explicit simulations - calibrating the mechanical properties of the pistol, in that the springs, contacts, materials and gun powder properties based on one firing cycle. The following is to calibrate the Non Rigid Boundary conditions (NRBC’s). This calibration of boundary conditions which are not completely fixed is crucial to understanding the actual strains and stresses on the parts. One of the approaches was to use known data of the stiffness of arm and wrist, implementing this data into a HyperStudy model to compare and calibrate the results based on a slow motion capturing of a real firing. The results are promising, with high accuracy of the behavior compared to a real capturing of the shooting, up to the point of slider getting to the end of its move – where most of the kinetic energy transform into loads on the frame. The following steps will be to calibrate, using the same method, the return of the slider to it’s original position and perform more than one firing cycle.

Achieving the targeted brand image in a short development cycle time with minimal or zero prototypes is a major challenge faced by EV companies. To overcome this challenge, Altair, HBK and Romax have jointly developed a simulation driven process coupled with capabilities to virtually experience the noise and vibration characteristics, giving engineers a way to obtain real time performance feedbacks as the vehicle is being developed. This joint presentation on the proposed NVH development process covers a wide range of topics, including benchmarking, target setting, full vehicle and motor gearbox simulation loadcases, troubleshooting, optimization and stochastic analysis, and playback of simulation results for subjective evaluations, with a number of new technologies representing the global best practice in sound and vibration design and development. Join us to explore ways to control the sound and vibration characteristics of the vehicle, achieve the right sound, and avoid common NVH pitfalls, while accelerating time to market utilizing and experiencing virtual NVH prototypes.

Thomas Goulding, Senior Mechanical Engineer at Assystems presents at the UK ATC 2019. Nuclear transport flasks are used to store and transport nuclear waste material. When transported on public roads the flask must fulfil International Atomic Energy Agency (IAEA) test requirements, which are designed to ensure that release of radionuclides is not credible. Whilst on-site, the flask requirements are driven by the Safety Justification which can be quite different to those defined by the IAEA.

A function-led design process was undertaken to fulfil these requirements for an IAEA Type B(M) package. This required a range of drop impact simulations using RADIOSS.

Altair HyperWorks was used as a common enabling tool for the analyses. The tools within HyperWorks were used to perform multi-disciplinary optimisation of the flask, without the need to revisit the Computer-Aided Design (CAD) model. Workable solutions, proven by simulation, were then incorporated into the CAD design. This function-led process was seen to be more efficient than the traditional trial-and-error approach. HyperMesh was used for mesh creation due to excellent element control and its capability to support a variety of solvers. The use of HyperCrash (pre-processor), RADIOSS (solver) and HyperView (post-processor) enabled non-linear impact analyses to be performed.

The oil and gas industry has shifted dramatically in the past year. The forecast for the industry is extremely different today compared to just a couple of years ago. To adjust, oil and gas producers are focusing on driving capital and operating efficiency to preserve their margins.

Corporations are making significant investments in innovative composite materials manufacturing technology for new product development processes and virtual prototyping for design and structural analysis. An effective virtual material (or material cards) for a numerical structural analysis method requires an accurate post-processing method from a complete mechanical characterization database to ensure a good correlation between the simulation and the real event.

Hot stamped steel parts are being increasingly used in automotive structures for their higher strength to meet safety standards while reducing vehicle weight to improve fuel consumption. However, manufacturing of sheet metal parts by hot stamping to achieve desired properties is extremely challenging as it involves complex interaction of plastic deformation, metallurgical change, thermal distribution, and fluid flow.
