ABSTRACT
This paper discusses the application of the numerical Green's function boundary element approach coupled with the operational quadrature method for the solution of dynamic crack problems governed by the scalar wave equation. Numerical examples are presented, allowing for the verification of the accuracy of the proposed procedure.

Keywords:  Boundary element method; Numerical Green's function; Operational quadrature method; Fracture mechanics
