Singularities of an inclined crack terminating at an anisotropic bimaterial interface

Characteristic equation for the stress singularities of the form r(lambda-1), 0 < Re [lambda] < 1, for an inclined crack terminating al an interface between two anisotropic media is derived. Explicit dependence of lambda 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 lambda are presented for certain kinds of bimaterial problems, and the influences of the material parameters, the meeting angles and the material alignments on lambda are examined. The role of the parameter beta(0) playing in the oscillatory behavior is also discussed. (C) 1997 Elsevier Science Ltd.
