We proposed a new method to analyze the scalar parameter of the asymptotic solution around a three-dimensional corner of jointed dissimilar materials under thermal stress using H-integral method with the finite element method. We performed eigenvalue analysis of the singular stress field using finite element method analysis for eigenvalue analyses. Then, we analyzed scalar parameters of the singular stress using the H-integral and the usual finite element analysis for the linear thermal elastic problem. Obtained asymptotic solution corresponds with the singular stress around a three-dimensional interface corner directly obtained by the finite element method.
