T-stress evaluation in nonhomogeneous materials under thermal loading by means of interaction energy integral method

摘要：

　　This paper addresses finite element evaluation of the non-singular T-stress in nonhomogeneous materials under steady-state thermal loads by means of interaction energy integral method.The interaction energy integral method developed in this paper can solve the T-stress with high accuracy and efficiently in nonhomogeneous materials.The interaction energy integral method in conjunction with the extended FEM is used to solve several representative examples to show its validity.It can be found that the present method is efficiency to calculate the T-stress in nonhomogeneous materials.
