The small scale yielding for mixed mode I and II plane stress crack problems in elastic perfectly-plastic solids is analysed by considering the stress field near the crack line. By expanding the stresses near the crack line and matching the stress field in the plastic zone with the elastic dominant
Abatraet-A new numerical method is presented for analysing the mixed-mode interface crack between two dissimilar isotropic materials. The method is formulated on the basis of finite element and the crack closure integral approach in conjunction with fundamental relationships in fracture mechanics. A
The near crack line analysis method has been used in the present paper. The classical small scale yielding conditions have been completely abandoned in the analvses and one inappropriate matching condition used to be used at the elasricplastic boundary has been corrected. The reasonable solution of
