Influence of dimensionality and specimen size on dynamic fracture

Abstract: In this contribution, we investigate the dynamic fracture process in Polymethyl Methacrylate (PMMA) plate specimens using a peridynamic computational model [2, 6]. We employ two as well as three dimensional peridynamic simulations in order to analyze the influence of dimensionality on the characteristics of the fracture process. The predicted crack speeds for the various levels of the initially stored energy, also known as the velocity toughening behavior, are compared with the experimentally observed crack velocities for PMMA specimens. The influence of the specimen size on the dynamic fracture process is investigated using 2D peridynamic simulations. The fracture strengths and the velocity toughening relationship obtained from different specimen sizes are compared with the Linear Elastic Fracture Mechanics (LEFM) size effect relationship and with results from the experiments [1], respectively.
