Oasys LS-DYNA Environment: User Guide (Version 8.1) LS-DYNA Manual Section: *CONTACT_ENTITY Example of: Rigid Sphere impacts Plate Example Filename: sphere_geometric.key Description: A rigid sphere drops onto an elastic plate. The sphere contains shell elements automatically generated with a Geometric Contact Entity spherical surface. Model: The plate of elastic material measures 40 × 40 × 2 mm 3 and contains 64 Belytschko-Tsay shell elements. The sphere has a radius of 6.0 mm and the distance from the center of the cube to the plate is 8.5 mm. The inertia properties of the sphere are defined by the properties of the rigid brick element. A geometric contact entity defines the spherical contact surface. The sphere moves toward the plate with a uniform motion. The termination time is 0.0005 seconds. Input: The Geometric Contact Entity defines the outer master surface on the rigid sphere (*CONTACT_ENTITY). The nodes on the plate are slave nodes (*SET_NODE_LIST) , and are in the Geometric Entity. A load curve definition defines the movement of the sphere (*PRESCRIBED_MOTION_RIGID, *DEFINE_CURVE). The displacement condition for rigid bodies is input by material numbers, not by listing the nodes included in the definition. Reference: Schweizerhof, K. and Weimer, K. Page A.43
