Complex Boundary Integral Equation Solution for Viscoplastic Analysis

In this paper, a general formulation of complex boundary integral equation for 2D viscoplastic problem based on initial strain rates is presented. And complex BEM analysis, which takes the constitutive model due to Hart as an example, is carried out. Compared with conventional BEM, there are some advantages of the present method such as simplicity and unification of formulations, simplification and general purpose of computer program, and being independent of fundamental solutions, etc. As suitable complex fundamental solutions which satisfy the boundary conditions on some part of the boundary and therefore no discretization is needed over that boundary can be chosen, more accurate results can be expected by employing less boundary elements.
