RT Conference Proceedings T1 Hardening study on the application of the Upper Bound Theorem in indentation processes by means of modules of Triangular Rigid Zones A1 Bermudo-Gamboa, Carolina A1 Martín-Fernández, Francisco de Sales A1 Sevilla-Hurtado, Lorenzo K1 Materiales K1 Ingeniería AB In previous studies based on indentation processes, the application of the Upper BoundTheorem (UBT) Modular Model by means of Triangular Rigid Zones (TRZ) has being analyzed.These studies were carried out with plane strain conditions and rigid-perfectly plastic material.One of the advantages of working with the modular procedure of the UBT, is the possibility ofthe introduction of the different parameters that take place in the process. This factorsintroduction allows the enrichment of the study, bringing the research nearest to the reality ofthe processes. Therefore, in order to approach the method to a real indentation process, theintroduction and study of the material hardening is inevitable. Furthermore, thanks to the newincremental processes that are being developed, the indentation processes are becomingimportant in the current industry.
