Solution of plane elasticity problems by the displacement discontinuity method. I. Infinite body solution
TL;DR: In this article, the displacement discontinuity method (DSM) is proposed for solving complex boundary value problems in plane elastostatics, which is similar to integral equation or influence function techniques, and contrasts with finite difference and finite element procedures in that approximations are made only on the boundary contours, and not in the field.
