✦ Synopsis

The stress intensity factors for bimaterial interface cracks are determined by the boundary element method employing the multi-region technique and the double-point concept. A formula relating the stress intensity factors to the crack surface displacement, which is applicable to both the homogeneous and the bimaterial systems, is derived. The accuracy of the numerical results obtained using the formula is shown to be satisfactory within 5% when compared with the pre-existing analytic solutions. The stress intensity factors for the edgecracked and the center-cracked bimaterial plates are computed with various crack lengths and shear modulus ratios under the biaxial and the uniaxial loadings, respectively.
