Interaction of coplanar surface cracks in a half-space

Scientific and Technical Section


Boundary integral equations are applied to the interaction of closely spaced surface-coplanar cracks with various geometrical dimensions in a half-space that is tensioned by forces perpendicular to the crack surfaces. The numerical results show that the crack depths and the distances between them greatly influence the stress intensity coefficients at the edges of the cracks, and the interaction between the cracks can be neglected only for shallow ones.
