notes
---------

The following figures represent the temporal evolution of the elastic stress intensity factor as well as the temporal evolution of the elasto-plastic stress intensity factor (called "plastically corrected") at the level of the point B of the defect as obtained with Code_Aster. These changes are also compared with their equivalents provided in the reference solution; the results obtained are very satisfactory.
