This paper presents the analytical method capacity of the upper bound theorem, under
modular approach, to extend its application possibilities. Traditionally, this method has been applied
in 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 whose
position comes from the center of mass calculated. The study of the load required to ensure the
plastic deformation will be focus on the profile of the part, independently on both sides of the fluence
plane, modifying the number and the shape of the modules that form the two halves in which the
part is defined. This way, it is possible to calculate the necessary load to cause the plastic deformation,
whatever its geometric profile.
