NUMERICAL APPROACH TO EXTREME LOADINGS BY AN OPTIMIZATION WITHOUT CONSTRAINTS

In the theoretical framework of the yield design theory, one takes int o consideration the case of materials whose field of resistance on the one hand contains within it it the stress tensor zero, and on the oth er is defined with the help of functions which are positively homogene ous. By integrating these properties into the classical numerical form ulation of ultimate loading calculations made using the stress method, a problem of optimization without conditions is obtained.
