Singularities of an inclined crack terminating at an anisotropic bimaterial interfac

Characteristic equation for the stress singularities of the form r ~ t, 0 < Re [2] < 1, for an inclined crack terminating at an interface between two anisotropic media is derived. Explicit dependence of ). on the material parameters is further carried out for materials, both having properties of orthotropy. Characteristic equation corresponding to any degenerate bimaterial problem is obtainable from present results. Numerical results of 2 are presented for certain kinds of bimaterial problems, and the influences of the material parameters, the meeting angles and the material alignments on 2 are examined. The role of the parameter r0 playing in the oscillatory behavior is also discussed. © 1997 Elsevier Science Ltd.
