　 1. DRY contact pressure calculation using Half Space Assumption
テキスト ボックス: Here, the calculation of the contact pressure by dynamic mesh is shown. Boundary points are moved so as to the pressures become 0 at the points. As a result, the shape of the contact surface is calculated. Load ： 100 KN Coefficient of Friction： 0.2 Young’s Modulus： 206 GPa Poisson Ratio： 0.3 Ball is assumed to be sliding to the –Y direction. The contact shape is cut at the shoulder and the edge load can be seen at the point. Lower figures show the contour figure and the mesh figure of the pressure Pz.
