**Calculation:
- material and geometric nonlinear
- Convergence bound at 1% to 2% of the L2-norm of the residual forces.
In ANSYS, the convergence criterion is defined as default value of 0.1 % of the L2-norm of the
residual forces. That means that all residual forces have to be transferred to the load vector except
0.1 % of the Root Mean Square. In the following calculations, a convergence criterion between
1% and 2% has been used. According to experience, convergence criteria between 1%
and 2% are precisely enough, to verify equilibrium conditions.
(Cohesion = 0 means no tensile- resp. compressive strength of the material. Hence result convergence
problems, so that the convergence bound has to be increased compared with the default
value to achieve a solution.)
