The<br />method is developed and combined with the modified J-integral theory to deal with this problem. The effects of<br />crack length, temperature and mechanical forces are investigated by Finite Element Method in the cracked<br />body. The conditions where the Mode I stress intensity factor motivate fracture occurrence is investigated and<br />variations of the different cases are discussed. The most deleterious situation is found to be that wherein the<br />entire model reaches rupture at some stage. The accuracy of the method is investigated through comparison of<br />numerical results with computerized simulation using commercial ANSYS software. ER -
