Abstract

Hypersingular integrals were investigated for general integers α (positive) and m (nonnegative). The integrals were evaluated to calculate the stress intensity factors. Examples involving crack problems were given and discussed with emphasis on the linkage between mathematics and mechanics of fracture. Analysis shows that as material property variation in space and higher order graded continuum theories are considered, the formulation of the crack problem and the associated kernels becomes quite involved.
