v9.01.111 SZLZ111 - Lemaître-Sermage damage in post-treatment POST_FATIGUE

Summary:

The purpose of this test is to calculate the Lemaître-Sermage damage « LEMAITRE » from a history of any multiaxial loading and the history of cumulative plastic deformation.

The damage is calculated from the data of the stress tensor and the plastic deformation accumulated at all times \({t}_{i}\) (provided by the user).

Material characteristics \(E\) (Young’s modulus), \(\nu\) (Poisson’s ratio), and \(S\) (material parameter) should depend on temperature \(T\). It must therefore be provided by the user at the same times as \(\sigma (t)\) and \(p(t)\).
