Verification and Validation of a 2D energy based peridynamic state-based failure criterion

Abstract

The paper presents a verification and validation approach for peridynamic failure models. The use-case at hand is an enhanced energy-based failure model for state-based peridynamics. Solution robustness and validity of predicted crack initiation and propagation is demonstrated for a double cantilever beam. Tensile tests using the same material and energy release rate from the prior simulations are used to predict specimen failure. The model is implemented in the software Peridigm and will be published open-source.
