Singular Thermo-Elastic Stress Analysis of An Irregular Shaped Inclusion

摘要：

　　This paper develops a super element that simulates the elastic behavior around an inclusion corner.The super inclusion corner element is finally incorporated with standard four-node hybrid-stress elements to constitute an ad hoc hybrid-stress finite element method for thermo-elastic stress analysis of an irregular inclusion in isotropic materials under thermal and mechanical loadings.In the numerical analysis,generalized stress intensity factors at the inclusion corner are systematically calculated for various material stiffness ratio and dimensions of the inclusion in a plate subjected to thermo-mechanical loadings.
