The Effect of Wiberg Angle on the Contact Pressure Pistribution in Natural and Artficial Joint

Abstract

The analogies and differences between the mechanical joints and the biological ones, in the presence of relative motion, are based on the pressure distribution. The paper analysed a numerical model of the pressure distribution and friction torque applicable to the spherical joint, specifically to hip. The effect of Wiberg angle about maximum pressure contact is analysed as a function to clearance joint.
