抄録

A new numerical method was presented for stress intensity factors (SIFs) analyses of a three-dimensional interface crack between dissimilar anisotropic materials subjected to thermal stress. The M-integral method was applied to the thermoelastic interfacial crack in three-dimensional anisotropic bimaterials. The moving least square method was used to calculate the value of the M-integral. The M-integral in conjunction with the moving least square method can calculate the SIFs from only nodal displacements obtained by the finite element analysis. We analyzed the SIFs of external circular interfacial cracks in jointed dissimilar anisotropic solids subjected to thermal load and showed the distributions of SIFs along the crack front. The distribution of stress and the crack opening displacement obtained by the asymptotic solution with the SIFs are compared with those obtained by the FEM with fine mesh. They are almost identical each other.
