The Upper Bound Theorem in Forging Processes: Model of Triangular Rigid Zones on Parts with Horizontal Symmetry Martín-Fernández, Francisco de Sales Martín-Sánchez, María Jesús Cano-Iglesias, María José Laminación (Trabajo de los metales) 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. 2021-02-24T08:39:01Z 2021-02-24T08:39:01Z 2021-02-23 2020-12-31 journal article Francisco Martín, María Jesús Martín, & María José Cano.
