13. Synthesis

For all the elastoplastic behaviors tested in models A to L, the results are satisfactory:

• the results are valid when the physical unit of the problem changes (\(\mathrm{Pa}\) in \(\mathit{MPa}\)), or following a rotation or symmetry of the load

• the results converge correctly with the time step, and the integration schemes (implicit for the elastoplastic behaviors studied) are robust, since they allow the use of large time steps

• the tangent matrices are correct because they are similar to the tangent matrices calculated by disturbance.
