Dynamic Simulation of Multiple Offset-Edge Crack of a Finite Plate

An extended finite-element method allows modeling the crack by the standard finite-element method without explicitly defining and meshing of the crack. This paper presents the extended finite-element approach for the prediction of the failure loads, fracture toughness for multiple-edge crack configurations using virtual crack closer technique, and cohesive approach for extensively used aircraft material. Experiments are performed considering the different edge crack configurations to validate the predicted extended finite-element results. The finite-element prediction of failure load and fracture toughness show good agreement with experimental results. Typical numerical results are presented to examine the effect of crack inclination angle, relative position of crack and material properties on failure load, and fracture toughness of a finite alloy plate. Based on extended finite-element and experimental results, mathematical models for estimation of failure load and fracture toughness for multiple-edge cr...
