4. Summary of results

The advantage of the test is to represent the comprehensiveness of possible loading paths with multiple slope failure factors: charge-discharge, mechanism transition.

On the other hand, the dimension of the problem allows to have only one unknown (the current internal variable), a solution to the inversion of the law of behavior curve: direct solution for the first mechanism and incremental for the second.

The reduction of the problem allows (if we converge) to trust Aster as a « slide rule » and to consider the result as an « exact » numerical solution.
