Examples ======== Example of use in 3D --------------------------- Take the case of an unmeshed crack, and a calculation of equivalent stress intensity factors in the presence of cohesive forces. The crack was defined by: fiss= DEFI_FISS_XFEM (MODELE =MO, TYPE_DISCONTINUITE = 'COHESIF', DEFI_FISS =_F (FONC_LN = funk1, FONC_LT = funk2, GROUP_MA_BORD = group_ma,), ); After the mechanical calculation having given a result res, the post-treatment to obtain the intensity factors of the equivalent stresses is carried out by: table_k= CALC_G (OPTION =' CALC_K_G ', RESULTAT = res, INST = inst_end, THETA =_F (FISSURE = fiss, NB_POINT_FOND = nb_pts,), LISSAGE = F (LISSAGE_THETA = 'LAGRANGE', LISSAGE_G = 'LAGRANGE_NO_NO'), )
