This paper uses Smoothed Particle Hydrodynamics (SPH) to analyze failure mechanism by predicting initiation and subsequent propagation of cracks without any special treatment or assumption on the fracturing process. An elasto-plastic damage model is incorporated into the SPH framework to enable non-linear behavior of the material. This constitutive model accounts for the irreversible process caused by plastic strain accumulation and the degradation of material properties due to damage initiation and development. A circular disc loaded diametrically is simulated within the proposed framework. It has been shown that the tensile stress distribution at the central area of the disc agrees well with the theoretical results. In order to study the effect of the loading angle on the failure process, three different central angles of the boundary load are considered in the numerical simulation. In addition to the circular disc, numerical simulations of a ring specimen under diametrically concentrated load are also presented.
