摘要
A line inclusion at the interface of an anisotropic bimaterial is studied. The line inclusion is assumed to be inextensible but with negligible bending rigidity. Complete singular fields near tips of the line inclusion are derived. The near-tip stress field exhibits singularities of the types r-1/2 +/- i-gamma* in general with r being the distance measured from the tips. The near-tip fields are similar to those for fully closed interface cracks. In analogy to the stress intensity factors defined for interface cracks, strain intensity factors are introduced to characterize the near-tip fields. It is shown that there are only two independent strain intensity factors and corresponding modes of deformation. Complete displacement and stress fields and the corresponding strain intensity factors as the line inclusion is under uniform remote loading are given. Strain intensity factors for a line inclusion very near some anisotropic bimaterial interface are also derived.
