The transportation industry is increasingly adopting advanced materials, which, as a result of increases in specific strength, offer improved efficiency, lower emissions, and decreased fuel consumption compared to traditional metal components. However, the transition to advanced materials has been slowed as structural analyses have become more complex and demanding.
Thin-ply HSCs are being used by Opterus in several commercial, NASA and DoD missions that achieve unprecedented packaging and deployed stiffness performance. Compared to traditional composites, HSCs exhibit improved damage tolerance, resistance to microcracking, improved aging and fatigue resistance, reduced minimum-gage thickness, and increased scalability.
MultiMechanics is partnering with Solvay and ANSYS to produce the webinar "How Solvay Uses MultiMech for ANSYS to Optimize Material Performance." The webinar will take place on Thursday, August 30th at 8:00AM CST.
Microstructural modeling is often viewed as an extraneous activity when analyzing the behavior of composites. Many engineers use the "system" properties as the inputs for their part design without considering what contributes to that overall system response.
Many companies that develop new composite materials are surprised when their product does not perform as expected during the physical testing and certification process. In addition to the many years wasted on developing the material, companies often spend more than $50M on developing and testing a single new material concept.
Failure in engineered materials is extremely difficult. In composites, damage originates at the microscale and is then propagated to the global scale. While Finite Element Analysis is a powerful tool, it is limited to the global scale because the mesh refinement needed to get down to the microscale is not feasible in FE programs. At MultiMechanics, we consider this to be a true multiscale problem, since damage at the microscale needs to be assessed and relayed to the macroscale.
