Computational Mechanics and Extreme Event Modeling
● ABSTRACT
Extreme event problems include engineering applications such as material cutting and molding, vehicle collision, landslides, air-blast, etc. In these problems, the structure usually undergoes large inelastic deformation, damage and fracture, strong hydrodynamical effects, high strain rate, and other extreme conditions. These phenomena pose difficulties in conventional numerical analysis, especially for mesh-based methods such as the finite element or finite difference method. They often suffer from mesh distortion, stress singularity, ill-conditioned deformation gradient. In contrast, novel methods such as meshfree methods can avoid these issues since the approximation is constructed directly from the discrete nodes, bypassing the mesh singularity and grid distortion. In this talk, I will introduce the field of computational mechanics of, ideas of meshfree methods and their application to various extreme events.
