3-D Node-to-Node Contact Elements (CONTA178) Input Listing: vm63.dat Test Case
A sphere of radius r is pressed against a rigid flat plane. Determine the contact radius, a, for a given load F. Figure 63.1 Static Hertz Problem Material Properties
E = 1000 N/mm2
υ = 0.3 Geometric Properties
r = 8 mm
F = (30 x 2 π) N Analysis Assumptions and Modeling Notes
An axisymmetric model is used. A node is placed near the expected radius of contact. Midside nodes are removed
along the surface where contact is likely to occur. The model is comprised of both PLANE82 and PLANE2 for
