Plastic Loop Motion

This is an Abaqus/Standard dynamic simulation animated in Abaqus/CAE. In step 1, the plastic loop is pulled down against a peg. The loop is released in step 2. The motion continues in step 3, but the output time interval is increased. The loop is meshed with B21 beam elements. The peg is meshed with C3D8R elements and is rigid. The contact is general contact.
