Elastic fracture mechanics analysis of bi-materials using boundary element method

The fracture and stress analysis for central cracks and diagonally apart cracks in an interface between two dissimilar isotropic elastic half planes were analysed. The analysis was subjected to tensile loading, perpendicular to the crack, on the material. The stress intensity factors (SIF) were calc...
