Non-hypersingular boundary integral equations for 3-D non-planar crack dynamics
The authors present a non-hypersingular boundary integral equation in fully explicit form for time-domain analysis of the dynamics of a three-dimensional non-planar crack located in infinite homogeneous isotropic medium. The hypersingularity is removed by a regularization based on the integration by parts. The calculations are performed in a local Cartesian coordinate system, one of the axes of which is always held locally perpendicular to the curved surface of the crack.
