Full Article:

This paper presents a new formulation of the Boundary Element Method to visco-plastic problems in a two-dimensional analysis. Visco-plastic stresses and strains are ob-tained until the visco-plastic strain rate reaches the steady state condition. A perfect visco-plastic analysis is also carried out in linear strain hardening (H’=0) materials. Part of the domain, the part that is susceptible to yield is discretized into quadratic, quadrilateral con-tinuous cells. The loads are used to demonstrate time effects in the analysis carried out. Nu-merical results are compared with solution obtained from the Finite Element Method (FEM).
