Abstract
Stress intensity factors and crack opening displacements for coplanar embedded elliptical cracks uniformly-spaced in an infinite solid are determined for remote tensile loading by a three dimensional weight function method developed previously. Crack opening displacements are also presented for its companion problem of a single embedded elliptical crack in a finite plate. Comparisons are made between them. Limiting behaviours as crack aspect ratio tends to zero are investigated, finding that appropriate stress intensity factors and crack opening displacements for two dimensional center cracks are approached. It is also numerically proved that the exact stress intensity factors and crack opening displacements are recovered as the distance between adjacent cracks tends to infinity.
