Abstract
One of the methods developed in recent years for the numerical solution of elastodynamics problems is the Peridynamic Theory. This method has, among others advantages, a natural capacity to simulate the initiation and growth of cracks in solid materials without the aid of additional methods and/or numerical procedures commonly employed in the conventional finite element formulation. This is mainly because the formulation behind the peridynamic theory is not based on partial derivatives of displacement fields, but based on the partial integrals of this field. Within this context, this paper presents a numerical investigation on the accuracy of the peridynamic theory to predict the stress and strain fields in isotropic plates with different geometric discontinuities when subjected to different loading and boundary conditions in the elastic and plastic regime. These results are compared with analytical solutions and numerical results based on the traditional finite element method and conclusions will be drawn.
