Introduction
A brief description of the example.
*RIGIDWALL_PLANAR_FORCES Cube Rebounding LS-DYNA Manual Section: *RIGIDWALL_PLANAR_FORCES Example: Cube Rebounding Filename: rigidwall_planar.cube.k Description: A cube impacts and rebounds from a rigid plate ( "Stonewall"). The plate is modeled with shell elements for viewing in LS-TAURUS. Model: The cube measures 10 * 10 * 10 mm3 and is 10 mm above the rigid plate. It has 8 brick elements with elastic material properties. The initial velocity of th e cube is 100,000 mm/second. The plate is an infinite "Stonewall" - surface. Input: The box option defines the nodes with the initial velocity (*DE FINE_BOX, *INITIAL_VELOCITY). The location of the "Stonew all" is at z=0 (*RIGIDWALL_PLANAR_FORCES). The nine nodes on the lower side of the cube are slave nodes to the "Stonewall" definition. The soft option of the rigidwall is used, which means that the slave nodes will come to stop within 10 time steps of initial contact with the rigidwall. Reference: Schweizerhof, K. and Weimar, K.
