Introduction
A brief description of the example.
*RIGIDWALL_PLANAR Rotating Shell Strikes Rigid Wall LS-DYNA Manual Section: *RIGIDWALL_PLANAR Additional Sections: *INITIAL_VELOCITY_NODE Example: Rotating Shell Strikes Rigid Wall Filename: rigidwall_planar.shell.k Description: A rotating shell element strikes and rebounds from a rigid wall surface. The plate is modeled with shell elements for viewing in LS-TAURUS. This does not affect the calculation. Model: The shell element has an elastic material model with Belytschko-Tsay shell formulation. The plate measures 10 * 10 * 2 mm3. The plate has an initial velocity of 100,000 mm/second in negative z-direction and an initial angular velocity of 100,000 radians/second about the y-axis. The rigid surface is modeled by an infinite smooth stonewall surface. Input: Nodes requiring initial velocity are specified with * INITIAL_VELOCITY_NODE. The location of the "Stonewall" is in the x-y plane with z= 0 (*RIGIDWALL_PLANAR). The 4 nodes belonging to the shell element are slave nodes in the stonewall definition. The velocity components of the slave nodes in the normal direction to the stonewall are reset to zero at the moment of impact. Reference: Schweizerhof, K. and Weimar, K.
