Computational-experimental approach to determination of residual stresses in welded joints
- 14 Downloads
A numeric-experimental method of determining the residual welding stresses in axisymmetric structures is proposed on the basis of analysis of the inverse problem of the theory of elasticity. The problem's solution is constructed by the self-regulation method using the finite-element method. Isoparametric approximations on curvilinear tetragons of the serendip family are used in this case. The results of investigation of the numeric effectiveness of the developed approach are presented.
