Abstract :

In the present paper, the main purpose is estimated path of crack growth under multi-axial loading. So, used plate with a center rectangular notch that has an initial crack with 5 mm length and 〖-55〗^°angle. At the First, has been obtained stress intensity factors of failure mode I and II by using ABAQUS software. Next has been calculated equivalent stress intensity factor and estimated path of crack growth by using the maximum environmental stress method. This trend has been continued to finish failure.
