Thick Plate Subjected to Torsional Impact by a Rigid Circular Cylinder

Abstract

The problem of a thick plate subjected to impact torsion by a rigid circular cylinder is analyzed based on the dynamic theory of elasticity. The dynamic stress intensity factor at the periphery of the contact region of the plate and the cylinder is investigated for the cases of a given rotational angle and torque. The results obtained are as follows: (1) In the case of a given rotational angle, the static result is larger than the dynamic one, and the dynamic result is larger for a thicker plate. (2) In the case of a given torque, the dynamic result is larger than the corresponding static one, and is larger for a thinner plate.
