A detailed study of mode II test specimen with elastic or plastic crack tips by using boundary element method

Abstract

Abstract In linear elastic fracture mechanics the stress and strain magnification at the crack tip is characterized by stress intensity factors which have been obtained for a large variety of loading and specimen geometries and of course mode II test specimen included. In this paper not only different kinds of boundary conditions of the contact surfaces of the elastic crack tip will be discussed but the plastic one. The rotation of the center line of the specimen will also be discussed. The results show the powerful application of the BEM model in the specimen.
