This example problem is an impact simulation using a 3-D model of a metal bar hitting a rigid wall using the Ansys Mechanical Application. To see this example solved using Ansys Mechanical APDL see Impact of a Metal Bar on a Rigid Wall in the Technology Showcase: Example Problems. The problem shows the advantages of using impact constraints for modeling contact in a nonlinear transient dynamic analysis.

Several combinations of time-integration methods and contact algorithms are also investigated, using different material models to show how various choices affect the performance and accuracy of the finite-element solution of impact problems.
