| Popis: | Based on an integral equation formulation, a boundary element method is presented for the analysis of curved cracks under mechanical and thermal load. It takes into account possible load and crack shape-dependent crack closure effects. In conjunction with a suitable crack growth criterion, the method enables, by means of an incremental numerical procedure, the solution of crack growth problems, of crack path prediction problems and of accompanied inverse control problems. Several examples illustrate the accuracy and applicability of the method in calculating stress intensity factors and crack paths. |
