2. Benchmark solution#
The values tested are non-regression values, except for the K and L models.
For the latter, the PRED_ELAS control method makes it possible to control the maximum damage increment, so that a reference value is available (the sum of the expected increments) at the end of the loading process. Typically, after 2 increments with target control of 0.1, the damage must be equal to 0.1 + 0.1 = 0.2 as soon as the maximum damage occurs in the same place for both increments (hence the choice of a Poisson’s ratio of 0 for the K and L models).
