| Περίληψη | A new boundary element approach for the solution of time-dependent inelastic problems arising in creeping metallic structures subjected to the combined action of high temperature gradient and quasi-static mechanical loading conditions is investigated. The new approach allows the use of complex variable techniques in the boundary element procedure for the evaluation of stress components as derivatives of the displacement integral equations. This methodology makes faster and more accurate the conventional boundary element method. To validate the efficiency of the proposed method in the implementation of Robinson's viscoplastic model, the results obtained using the present methodology are compared with those obtained by using known analytical and finite element solution for the analysis of a thick-walled internally pressurized cylinder and an experimental cylindrical thrust chamber in plane strain under general thermomechanical loading histories. | en |
