*HEADING COPPER ROD IMPACT (3D MODEL) ** ** This example simulates the high velocity impact of a copper rod ** onto a rigid wall. Similar tests have been performed to determine ** the material constants for high-pressure equations of state, and ** the test is sometimes described as the Taylor bar experiment. ** Extremely high plastic strains develop at the crushed end of the ** rod, resulting in severe local mesh distortion. ** *RESTART, WRITE, NUMBER INTERVAL=4, TIMEMARKS=NO *PREPRINT,ECHO=NO,MODEL=NO,HISTORY=NO ** **
