โœฆ Synopsis


An elasto-dynamic moving element formulation incorporating a variable order singular element to enhance the local crack tip description is presented. The moving mesh zone is embedded in a finite global mesh providing a functional tool for the analysis of dynamic crack growth experiments.

In the following, the necessary numerical techniques are developed and tested using problems possessing analytical solutions. The promising results reported here motivate further work to include viscoplastic material behavior in the formulation.
