Abstract: According to the theory of function of complex variables,the eigenfunc- tion expansions of displacements and stresses,satisfying the governing equations,boundaryconditions along cracked interface and conditions of continuity along uncracked interface, are derived.The conservative integrals of mixed mode for interfacial crack of imcompress-ible bi-metal and the relations between conservative integrals and stress intensity factors areestablished.Furthermore,the unknown coefficients,including stress intensity ...
