摘要

An antiplane multiple crack problem is considered for a class of inhomogeneous anisotropy elastic materials. The problem is reduced to a boundary integral equation involving hyersingular integrals. The boundary integral equation may be solved numerically using standard procedures. Some creak problems for a particualr inhomogeneous material is considered in detail and the stress intensity factors are obtained in order to assess the effect of the anisotropy and inhomogeneity on the stress field near the crack tips.
