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.
