Determine the semi-contact length b and the approach distance d. Figure 191.1 Hertz Contact Between Two Cylinders Problem Sketch Material Properties Cylinder 1: E1 = 30000 N/mm2 υ1 = 0.25 Cylinder 2: E2 = 29120 N/mm2 υ2 = 0.3 Geometric Properties R1 = 10 mm R2 = 13 mm Loading F = 3200 N/mm ANSYS Verification Manual . ANSYS Release 9.0 . 002114 . © SAS IP, Inc. 1–433 VM191 Analysis Assumptions and Modeling Notes Each analysis uses two load steps; in the first load step a small imposed displacement is used on the upper cylinder to engage contact, whereas in the second load step the imposed displacement is deleted and the force load is applied. The problem is solved in eight different ways: Con...
