Abstract

The relatively new theory of peridynamics is a non-local continuum theory for the modeling of materials behaviour and is especially powerful in treating the spontaneous formation of discontinuities. This indicates that it might be useful in the dynamic modeling of dislocations, but in order to achieve this, its basic principles should be comprehended first. A literature study on the theory has been performed and a peridynamic code has been developed. Using the code in the simulation of a tensile test under quasistatic conditions has verified the linear elastic properties of the peridynamic model material and the correctness of the code. An impact test is used subsequently to explore the influence of several parameters. A dynamic fracture test has been studied next to determine the limit of the crack propagation speed, which turns out to be bounded by the Rayleigh wave speed. The insight that these results give in the properties of peridynamics opens the road to extension of the code to solve problems which have not yet been solved.
