摘要：
In this study, the effect of Poisson's ratio on two-dimensional elastic-plastic stress is studied by using the body force method, in which the stress field caused by plastic deformation is replaced by a stress field due to force doublets. It is shown that the elastic-plastic stress induced by a prescribed surface traction for a given strain hardening rate H'/E is independent of Poisson's ratio nu, provided that the stress is in a state of plane stress and the vector sums of traction on holes are zero for every individual hole.
