Institute of Problems in Mechanics, USSR Academy of Sciences, 117526, Moscow, USSR aut An interface crack in an inhomogeneous stress field [Elektronische Daten] [I. Simonov] The solutions for interface cracks of shear, opening and mixed modes (problems A, B, C) are obtained in elementary functions. In case C the crack surfaces partially overlap, slipping without friction. After removing the inhomogeneous stress field specified at the infinity the crack surfaces are loaded by normal and tangential stresses distributed according to a polynomial law. A detailed analysis is carried out for the solution corresponding to linear variation of these stresses. It develops that the strain-energy release rate varies slowly when going from problem C to problem A under compression-shear-bending of the piecewise-homogeneous plane, and from problem C to problem B when compression is replaced by tension. There is also a slow variation in the largest of moduli of the stress intensity factors with the elastic parameters. These results allow one to estimate the structure-toughness characteristics for inhomogeneous bodies by solving problems in simplified formulations.
