Ensuring the Highest Bus Safety - Altair Simulation Helps Gemilang Achieve Excellent Rollover Rating
In an effort to increase transportation safety, today’s bus rollover and crash test regulations have become more stringent. To ensure all products achieve the requisite safety regulations, Gemilang set up dedicated in-house testing facilities, including a tilt test platform to assess the stability of the vehicle, and a rollover test platform to ensure bus safety in the event of a rollover accident. Gemilang decided to leverage computer-aided engineering (CAE) simulation technologies to facilitate the bus rollover assessment during the early stage of product development and selected Altair as its technology partner.

Using FEA for train homologation - modeling bolted assemblies, composites parts, and topology optimization
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).

Use Cases
Efficient Engineering Based Modeling of Layered Composite Structures
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.

VABS: Modeling Composite Beam-like Structures with 3D FEA Fidelity
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.

Composites at Altair
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.

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.

Curing, Cracking and Distortions in Epoxy Composites. Simulating Manufacturing Processes using Finite Element Approach
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.
