Hardening prediction of diverse materials using the Digital Image Correlation technique
In recent years, due to the introduction of higher resistance materials in the automotive sector, sheet metal-forming tool-makers have been forced to deal with more challenging process designs. Therefore, the optimisation ...
Caracterización y optimización de los procesos de hidroconformado de tubo
(Mondragon Unibertsitatea. Goi Eskola Politeknikoa, 2006)
Los procesos de hidroconformado de tubo consisten en conformar un tubo de aleación metálica mediante la aplicación interna de un fluido (emulsiones de agua y aceite) a alta presión. El proceso se divide principalmente en ...

Hammer forging is a widely employed manufacturing process to produce parts with excellent mechanical properties. In order to achieve an optimal process design, finite element modelling is broadly utilized in industry and ...
High-Speed Material Characterization Using an Instrumented Forging Hammer
Hammer forging is a widely employed manufacturing process to produce parts with excellent mechanical properties. Although the rheological behavior and the microstructural transformation phenomena of metals under hammer ...
Elastic behaviour characterisation of TRIP 700 steel by means of loading-unloading tests
(Elsevier Ltd., 2015)
The elastic behaviour of TRIP 700 steel under plastic deformation is analysed. The analysis is carried out by means of classical tensile test and loading–unloading cyclic tests. These tests have been performed using high ...
New drawbead tester and numerical analysis of drawbeads closure force
Currently, a great deal of controversy exists regarding the real forces generated in drawbeads during sheet metal forming processes. The present work focuses on the analysis of the uplift force. First, a detailed literature ...
Comparison of the hardening behaviour of different steel families : from mild and stainless steel to advanced high strength steels
(Elsevier Ltd., 2015)
Although steel has been used in vehicles from the automotive industry's inception, different steel gradesare continually being developed in order to satisfy new fuel economy requirements. For example,advanced high strength ...
The influence of the kinematic hardening on the FEM simulation of Tension Levelling Process
(Elsevier Ltd., 2020)
Tension levelling is used in the steel industry to remove shape defects present in cold rolled strip. This technology is increasingly being employed by steel makers to level AHSS steels, because conventional roll levelers ...
