✦ Synopsis

An antiplane multiple crack problem is considered for inhomogeneous isotropic elastic materials. The problem is reduced to a boundary integral equation involving hypersingular integrals. The boundary integral equation may be solved numerically using standard procedures. Some crack problems for a particular inhomogeneous material are considered in detail and the stress intensity factors are obtained in order to assess the eect of the inhomogeneity on the stress ®eld near the crack tips.
