The application of the boundary element method (BEM) for the 3D‐stress analysis of cracked structures considering elastic‐plastic material behavior is presented. For separating the coincident crack surfaces the DUAL‐BEM is utilized. The relevant boundary integral equations (BIE) – the strongly singular displacement BIE and the hypersingular traction BIE – are evaluated in the framework of a collocation procedure.
