Single shot impact in Abaqus
Single shot impact in Abaqus
(OP)
Hi
I would like to simulate a single steel shot impact on a steel metal surface and measure the residual stresses and the rebounding velocity of the shot after impact (coefficient of restitution). Simulation should be in 3D. The initial velocity of the shots are about 70 m/s. Is high stress strain rate data required to model the deformation? What is the best approach to this problem?
Thank you for your help.

Thanks for your reply. I couldn't find any material test data and will use the material properties that is available on Matweb.
Many Abaqus examples use fixed displacements for loading and unloading.
In terms of measuring the rebounding velocity, what method would be most appropriate one to use?
