Abstract

There is a great deal of interest in the behavior of metallic materials under high strain rate loading. Finite Element Analysis (FEA) could be used to model these materials with a reduction in the amount of experimentation needed for characterization. A finite element model of a metallic ring under high strain rate loading was developed using the Johnson-Cook failure model in Abaqus Computer Aided Engineering (CAE). The ring was modeled both axisymmetrically and in three dimensions. Failure was determined by defining a failure initiation value to start the process of element deletion. It was found that element deletion would occur when the failure strain initiation value was less than 1×10-4. Results of both axisymmetric and 3-D were found to be within 3% of each other with respect to maximum von Mises stress, and failure modes were identical. The effects of model changes and loading conditions are investigated.
