The Development of the Material Point Method for Simulating Nonlocal Failure Evolution Involved in Multi-phase Interactions
The evolution of interfacial failure between different materials such as concrete and soil has the nonlocal feature. As a result, local constitutive models cannot predict the real physics associated with the interfacial failure evolution. Since its first journal paper was published in 1994, the Material Point Method (MPM, http://en.wikipedia.org/wiki/Material_Point_Method), which is a spatial discretization extension from computational fluid dynamics to solid dynamics, has evolved with applications to different areas in Simulation-Based Engineering Science (SBES). We are developing a particle-based computer test-bed for multiscale and multiphysics modeling and simulation to advance SBES, with a focus on the multiphase interactions involving failure evolution. In this conference, the very recent results in improving the MPM will be presented with applications to nonlocal failure events, and future research and development directions will be discussed to promote international collaboration.
