Peridynamics states and constitutive modeling

WebMay 1, 2011 · Abstract. An implicit time integration algorithm for a non-local, state-based, peridynamics plasticity model is developed. The flow rule was proposed in [3] without an integration strategy or yield criterion. This report addresses both of these issues and thus establishes the first ordinary, state-based peridynamics plasticity model. WebApr 11, 2024 · Test cases were designed to illustrate the efficiency of different training architectures, as summarized in Table 1 and Fig. 2.For Cases 1–3, we can find that the data-driven model with the simplest hidden-layers architecture (2 6, 2 7) possesses the lowest computational time for FE simulation.However, the simpler architecture also results in a …

The peridynamic theory is based on integral equations, in contrast with the classical theory of continuum mechanics, which is based on partial differential equations. Since partial derivatives do not exist on crack surfaces and other singularities, the classical equations of continuum mechanics cannot be applied directly when such features are present in a deformation. The integral equation… WebTo enhance the calculation accuracy of bond-based peridynamics (BPD), a novel attenuation function is introduced to describe the effect of internal length on nonlocal long-range forces.
