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.
