| Abstract: | The complete formulation of B.E.M. applied to the analysis of axisymmetric bodies acting in the plastic range is presented in this paper. The concept of derivative of a singular integral given by Mikhlin has been used in order to calculate the stresses in internal points.Also a semianalytical approach is proposed to compute the matrix coefficients, presenting the way in which it can be done and the results obtained. |
