Problem statement

Geometry: Rigid cylinder R=100 mm, elastic half-space E=1000 MPa, nu=0.3, line load 10 N/mm.
Material: Constitutive or analytical definition: b=sqrt(4 w R/(pi E*)); p0=2w/(pi b).
Boundary conditions: Required solver capability: 2d_or_extruded_frictionless_contact. Use the loading/path control stated in the setup and preserve the complete response history.
Measured quantity: Half-width b=1.07640512155 mm and peak pressure p0=5.9143138547 MPa.
