Abstract

In this work a methodology by using the computational finite element method of a tooling designed for the process tube bending in the automotive industry, in order to determine the magnitude and location of the geometric stress concentration is implemented. The tooling is modeled computationally with a steel degree AISI-D2 (current design) and subsequently with steel AISI-4140. Because the null information about the mechanical properties of these materials, the methodology for their determination is presented. The modeling and simulation with the steel AISI-D2 indicates a geometric location coincident of the stress concentration with the fracture zone when the tooling fails by operating, therefore, the magnitudes of the numerical results are considered reliable. Finally, modeling with the steel AISI-4140 proposes it as a viable alternative because not compromise the functioning of the system and also has a low cost and easy to manufacture.
