In order to advoid the complication coming from considering the boundary conditions, most of the analysistical solution derived from mathematical models in Linear Elastic Fracture Mechanics are with respective to infinite domain. Consequently, it have to consider the affect of boundery.So the first goal of our research is to see the influence of different integration area affect for intensity factors ,J integrals,T-stress and Ct integrals to make sure the stability of Damage parameters.And the second goal of our research is to see the influence of different finite size about the Damage parameters,i.e.,the factor 2a/w to the value of J integrals.By using the test example results,we can make sure different finite size affect about the Damage parameters,hoping we can use in actual engineering industry.
