An elastodynamic fracture analysis in a centre-cracked plate

Research output: Contribution to journalArticlepeer-review

Abstract

A two-dimensional linear elastodynamic analysis of crack initiation and fast crack propagation in a centre-cracked plate, subjected to constant tension is presented. The analysis is performed using the previously developed SMF2D code in its generation mode. The experimentally measured crack tip motion, as well as the specimen's geometry and its material characteristics serve as input to the simulation. The dynamic stress intensity factor, the dynamic energy release rate, and the various energy distributions are subsequently evaluated. Special attention is given to the influence of the energy supplied to the body during the fracture process due to the work done by the external tractions.
