v6.03.148 SSNP148 - Calculation of the stress intensity factor by stress regularization with ENDO_HETEROGENE

Summary:

This test calculates the propagation threshold of a central crack in a plate of infinite length stressed by an infinite stress. In this case an analytical solution exists since the stress intensity factor can be calculated. This test gives a comparison between this analytical solution and the value of the stress intensity factor calculated from the regularized stresses (D_ PLAN_GRAD_SIGM modeling). The objective of this approach is to validate the calculation method (modeling D_ PLAN_GRAD_SIGM and law ENDO_HETEROGENE.) for cases where the characteristic length is short compared to the size of the crack and the structure.
