摘要

Three-diemsnional asymptotic stress field in the vicinity of the front of a bimaterial pie-shaped wedge of general (unsymmetric) geometry is obtained by a recently developed eigenfunction expansion method. The bimaterial pie-shaped wedge is subjected to four combinations of wedge-side boundary conditions - free-free, clamped-clamped, free-clamped and clamped-free. Each material is isotropic and elastic, but with different material properties. Additionally, numerical results pertaining to the variation of the lowest eigenvalues (or stress singularities) with respect to the wedge opening angle of the bimatrial wedge, subjected to the aforementined edge-side boundary conditios, are also presented. Dependence of the same on the material properties of the component material phases is also an important part of the present investigation,
