      What is the cause of overshoot in contact pressure value for CZM?

      The overshoot in the value of contact pressure is due to artificial damping coefficient. Debonding is generally accompanied by convergence difficulties in the Newton-Raphson solution. Artificial damping is used to stabilize the numerical solution. In general a very small value of 1E-8 is used.
