AB This paper presents the analytical method capacity of the upper bound theorem, undermodular approach, to extend its application possibilities. Traditionally, this method has been appliedin forging processes, considering plane strain condition and parts with double symmetry configuration.However, in this study, the double symmetry is eliminated by means of a fluency plane whoseposition comes from the center of mass calculated. The study of the load required to ensure theplastic deformation will be focus on the profile of the part, independently on both sides of the fluenceplane, modifying the number and the shape of the modules that form the two halves in which thepart is defined. This way, it is possible to calculate the necessary load to cause the plastic deformation,whatever its geometric profile.
