2. Benchmark solution#

2.1. Calculation method used for the reference solution#

Without friction, the contact pressure at the interface is equal to the pressure imposed.

2.2. Benchmark results#

The contact pressure is constant and equal to \(25\mathit{MPa}\) over the entire contact surface.

2.3. Uncertainty about the solution#

Analytical solution.
