Summary of results ====================== * This POST_JMOD development allows to calculate J for symmetric and non-symmetric problems, linear and quadratic meshes, opened and closed cracks, linear and non-linear problems (Models A to J). * The solutions are well agreed with the reference ones with a fine mesh (Model C). * POST_JMOD provides in general better results than CALC_G and POST_K1K2K3 and does not significantly depend on the outline. * The desired outputs may be selected for calculating and printing via the options of POST_JMOD. *
