Abstract
Nowadays, thanks to the new manufacturing processes, indentation is becoming an essential part of the new arising processes such as the Incremental Forming Processes. This work presents the experimental validation of the analytical model developed for an indentation-based process. The analytical model is originated from the Upper Bound Theorem application by means of its new modular distribution. The modules considered are composed of two Triangular Rigid Zones each. The experimental validation is performed through a series of indentation tests with work-pieces of annealed aluminium EN AW-2030 and punches of steel AISI 304, under plane strain conditions. The results are compared with the ones obtained from the application of this new modular distribution of the Upper Bound Theorem, showing a good approximation and suitability of the model developed for an indentation-based process.

In the study of the indentation process by the application of the Upper Bound Theorem (UBT), the Triangular Rigid Zones (TRZ) alternative is the kinematic-geometrical option [12] that allows reaching a more accurate solution and adds a strong capacity of analysis of the principal factors involved in the deformation process
Once the analytical model applicable under the UBT by its TRZ module configuration has been established and the final model optimization for the study of the indentation process implemented, a validation of the application through experimental testing, is necessary in order to determine the suitability of the method
Summary
A new modular distribution of the application of the Upper Bound Theorem (UBT), by means of modules of Triangular Rigid Zones (TRZ) is performed in this paper This new method presents an alternative to the computational methods currently used in the industry, such as numerical methods or the Finite Element Method (FEM). The study and analysis of IFP, where the indentation process takes place, is being a recurrent topic of research [10,11] The implementation of these processes is becoming imperative to the industry in order to (be able to) offer a competitive production. In the study of the indentation process by the application of the UBT, the TRZ alternative is the kinematic-geometrical option [12] that allows reaching a more accurate solution and adds a strong capacity of analysis of the principal factors involved in the deformation process. Once the analytical model applicable under the UBT by its TRZ module configuration has been established and the final model optimization for the study of the indentation process implemented, a validation of the application through experimental testing, is necessary in order to determine the suitability of the method
