*CONSTRAINED_JOINT_PLANAR Sliding Blocks with Planar Joint LS-DYNA Manual Section: *CONSTRAINED_JOINT_PLANAR Additional Sections: *LOAD_NODE_POINT *LOAD_SEGMENT *INITIAL_VELOCITY_NODE *CONSTRAINED_EXTRA_NODES_SET Example: Sliding Blocks with Planar Joint Description: This problem illustrates a planar joint connecting two rigid bodies. Model: The first block measuring 2*2*2 slides along a second block measuring 2 * 2 * 8. A third flexible body controls the time step size. The first block has a ramped pressure of 100 psi applied to the top surface and ramped concentrated forces applied to a lower edge of 40 lbs. The initial velocity of the first block is 400 inches/second. Input: One joint definition consist of nodes 128, 126, 129 and 127 (*CONSTRAINED_JOINT_PLANAR). The nodes are extra nodes attached to the rigid bodies and are coincident (*CONSTRAINED_EXTRA_NODES_SET, *SET_NODE_LIST). Results: The plots show that the first block correctly slides across the second block.
