Problem Specification {Now, consider a simple problem that illustrates a comparison between the analytical and numerical results. As shown in the diagram below, consider a problem where we apply a downward force (F) of 60π newton to a spherical object with a radius (R1) of 8 millimeters. This isotropic sphere has an axial modulus (E1) of 1 GPa and a Poisson's ratio (ν1) of 0.3. In addition, this sphere is fixed vertically at the contact interface with a rigid wall. Since we are modeling the wall as a rigid body, we assume axial modulus (E2) equals +∞ and Poisson's ratio (ν2) equals 0. Also, the radius of curvature of the wall (R2) can be assumed to be zero.}Under Construction{note} \\ \\ [*Go to Step 1: Pre-Analysis & Start-Up*|Hertzian Contact Mechanics - Pre-analysis & Start-Up] [Go to all ANSYS Learning Modules|ANSYS Learning Modules]\\ \\ |
