WebIn this version of the model, the bond irreversibly breaks when s > s0, with s0 called the critical stretch for bond failure. A first order micro elastic peridynamic damage model is shown in Figure 2. When s0=s1 this model results in the “zeroth order micro elastic damage” peridynamic model used in the remainder of this paper. 2. WebJul 1, 2007 · With this new model, very simple tensile damage mechanisms at the micro structural (peridynamic) level are sufficient to explain a great deal of the microcracking (damage) and fracture mechanics observed in concrete structures. The new implementation appears to be computationally efficient. 1. Introduction
