Dynamic Crack Propagation Using Boundary Elements
A boundary element procedure for the dynamic analysis of crack propagation in arbitrary shape finite bodies is presented. The procedure is based on the direct time domain formulation of the Boundary Element Method. A moving singular element and a remeshing technique have been developed to model the solution of the stresses near the propagating crack tip. The method is applied to a problem of dynamic crack propagation in a finite elastic domain. The obtained numerical results are compared with available solutions obtained by other authors.
