Abstract

In this paper, the level set method is coupled with the boundary element method to simulate dynamic powder consolidation of metals based on linear elastostatics theory. We focus on the case of two particles that are in contact. The boundaries of the two particles are expressed as the zero level curves of two level set functions. The boundary integral equations are discretized using the piecewise linear elements at some projections of irregular grid points on the boundaries of the two particles. Numerical examples are also provided.
