| Abstract: | In this paper a method is Presented for deriving boundary integral equations based on the generalized variational principle.For axisymmetric elasto-plastic problems,the formula for the reduction of dimensions of the problems are derived.A BEM Program for two dimensional elasto-plastic problems(including plane problems and axisymmetrie Problems)is worked out by using the initial stress method and subincremental procedure,some examples are given and some conclusions are reached. |
