/INTER/HERTZ/TYPE17 - Interface Type 17 - Hertz Formulation

Description

This interface simulates impact between external surfaces of two brick groups. The external surfaces can only be 16-node thick shell (/SHEL16) elements. A Hertz contact theory is used in this interface. This interface does not use Lagrange multiplier kinematical conditions and is compatible with all kinematic conditions. The formulation is like a penalty formulation; but with a physical penalty stiffness based on Hertz contact theory.
