Success in developing the new generation of cars and trucks has demanded advancements in many arenas, including powertrains, fuels, materials, manufacturing methods and design. Computer-aided engineering tools from Altair have advanced as well allowing design engineers to improve vehicle efficiency and performance while at the same time lightening the vehicle structure. Laminate composites are beginning to play a larger part than ever in vehicle design, and Altair offers the software tools that are enabling composites to become a key material across the auto industry. Altair’s Vice President of Global Automotive, Dave Mason offers answers to some of the most important questions about Altair’s role in the use of composites for today’s vehicles.
HyperWorks Partner Alliance Expands Composites Offering Further by Adding MultiMech Suite to the Program.
MultiMech Research & Development’s multiscale composite technology has been added to the HWPA’s CAE software solution set.
MultiMech Research & Development is the latest partner to join the HyperWorks Partner Alliance. Their software, MultiMech Suite, is a set of composite tools that allows users from many industries to analyze and optimize materials using its state-of-the-art two-way coupled multiscale technology. MultiMech Suite provides solutions to accurately and cost-efficiently relate materials’ microstructural design variables to overall structural performance. This helps solve problems related to mechanical failure and inefficient trial and error product development. To learn more about MultiMech R&D or MultiMech Suite, please visit their website.
Interview with Leandro Castro, Co-Founder of MultiMec h Research & Development
Kanto Auto Works, Ltd. is a core member of the Toyota Group, developing and producing Toyota vehicle bodies. The company’s organic-material engineering department evaluates and develops plastic parts to be used in vehicle bodies. In the initial stage of development for large plastic parts, such as instrument panels, rigidity and heat resistance are verified using computer aided engineering (CAE). While plastic is significantly lighter than metal and can be molded into complex shapes, deformation, such as warping from external force or thermal expansion in high temperatures, also occurs easily. In order to make parts lighter while still ensuring sufficient rigidity and heat resistance, there is a need to identify which areas require reinforcement.
HyperWorks customers can access ESAComp composites modeling through the HWPA
Componeering Inc.’s software ESAComp is a composite modeling tool that aids engineers in the design and structural analysis of composites. It’s used from preliminary design to the more advanced analyses that are necessary for final design verification. Its comprehensive material database forms the basis for design studies. ESAComp has a vast set of analysis capabilities for laminates and sandwich constructions and it also includes micromechanical analyses. It further contains additional tools to address structural elements, including but not limited to cylinders, columns, and panels. This solution is available for immediate download through the HWPA website.
Anaglyph Furthers Relationship With Altair by Adding its Composite and Laminate Analysis Software to Altair’s HyperWorks Partner Alliance
HyperWorks users now can access CoDA and LAP through the partner program with their HyperWorks licenses
The Laminate Analysis Program (LAP) is used to analyze any type of composite laminate. Typically, the software is used in the preliminary design for tailoring a stacking sequence, then analyzing the composite component with other methods, such as FE, and finally optimizing the design by inspecting the laminate behavior layer by layer. CoDA synthesizes the properties of composite layers or laminates to be used in a seamless manner within the design modules. This integration allows for instantaneous assessment of the effect of changes on any input parameters. CoDA also provides “what-if” scenarios for users to rapidly evaluate graphically any output result as a function of variable input data. Altair HyperWorks customers can now access CoDA and LAP through the HWPA with their existing HyperWorks units.

Composites are flying high in the aircraft industry as manufacturers look for ways to reduce weight, improve performance and create a better customer experience. Composites, of course, weigh considerably less than conventional aluminum and titanium materials, and they offer a number of other benefits as well. These include high stiffness-to-weight ratios, better fatigue performance, non-corrosive characteristics, and less susceptibility to crack growth.
That said, composites are subject to their own distinct problems. The damage modes are far different from those of metals. Delaminations and matrix cracks are common damage modes, and both can occur internal to the structure with no visible damage on the surface. This poses a problem for inspection, so many aircraft manufacturers are embedding sensors into the structure to detect damage. The manufacturing processes also are much different for composites, necessitating different equipment and tooling. The joining methods for composites require different techniques and analysis methods to design and certify.
The video describes some of the features available in HyperMesh 11.0 in order to efficiently manage FE modeling of composites components. Capabilities include importing CPD data from CAD files, visualizing ply directions and properties, and 3D realistic ply thickness and staking order visualization.
