ART ICLE INFO ABSTRACT Article history The amount of damage induced by brittle fracture of cracked bodies depends considerably on Received March 20 2013 the path of fractures. Therefore prediction of the trajectory of fracture using suitable theoretical Received in Revised form fracture criteria is very important for cracked structures. In this paper using higher-order terms September 14 2013 of Williams s series expansion and the maximum tangential stress criterion the mixed mode Accepted 18 September 2013 Available online I II crack growth path of an angled crack plate subjected to biaxial far field loading is 18 September 2013 investigated theoretically. To evaluate the accuracy of the theoretical results they are compared Keywords with the experimentally reported trajectories for the angled crack plate specimen. It is shown Williams series that by taking into account the higher order terms of the Williams series expansion a very good Crack growth path agreement is observed between the experimental and theoretical mixed mode fracture paths in Mixed Mode the angled crack problem. It was also observed that the theoretically determined initial angle of Maximum tangential stress crack growth is consistent with the experimental results. criterion Higher order terms 2013 Growing Science Ltd.
