| Abstract: | An analogy scheme,proposed by Tian in 1999 for the determination of the elastic-plastic crack-tip fields,is used for solving gneral elastic-plastic problems.Solutions of two typical problems are worked out and checked by the finite element method.The mechanic fields are proved to be the real solutions in the general elastic-plastic sense. |
