IMPROVED DYNAMIC ANALYSIS OF AN INITIATING AND FAST-RUNNING GRIFFITH CRACK IN A FINITE RECTANGULAR PLATE.

Research output: Contribution to conferencePaperpeer-review

Abstract

Crack initiation and dynamic crack propagation in a centrally cracked plate subjected to constant tension is investigated, employing two-dimensional linear elastic fracture mechanics. The analysis is performed using the SMF2D code which is based upon the simultaneous employment of both a stationary and a moving coordinate system. The different parameters of stress intensity factor, energy release rate as well as energies distributions, were evaluated throughout the various simulations. Special attention was given to the influence of the energy supplied to the body by the work carried out by the external tractions during crack propagation.
