APLICACIÓN DEL TEOREMA DEL LÍMITE SUPERIOR MEDIANTE SU CONFIGURACIÓN MODULAR A PROCESOS DE INDENTACIÓN CON PUNZÓN INCLINADO.

Abstract

Indentation processes are regaining interest nowadays due to the development of new deformation processes in the current manufacturing industry, as the Incremental Forming Processes or the Localized-Incremental Forming processes. This present article considers the analysis of the indentation process performed with a tilted punch. The aim of this study is to extend the analysis to as many differ indentation cases as possible. The development of the mathematical model for a tilted punch allows to conduct geometric combinations with previous studies that were carried out for flat punch cases. Hence, expanding the analysis of complex geometries. Thus, in this paper, the indentation process with tilted punch, studied by the Upper Bound Theoremt under its new modular configuration is presented. This new modular configuration consists of three modules of two Triangular Rigid Zone each, for the complete adaption to the considered punch shape.
