Abstract

The present paper discusses the application of the Hyper-singular Boundary Inte- gral Equation to obtain the Green's function solution for elastodynamic Fracture Mechanics problems. The work introduces efficient numerical means of computing the Green's function components for multiple crack problems, of general geom- etry. Applications to time harmonic and transient (through inverse numerical transform) problems are presented. 1 Introduction The implementation of a fundamental solution that includes the crack ex- istence, known as Green's function, is an important alternative in treating Fracture Mechanics problems by the Boundary Element Method [1]. Originally, the traction (hyper-si
