Monitoring of a Hammer Forging Testing Machine for High-Speed Material Characterization
(Elsevier Ltd., 2020)
Dynamic testing of materials is necessary to model high-speed forming processes (i.e. hammer forging, blanking) and crash/impact behavior of structures, among others. The most common machines to perform medium to high-speed ...
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 ...
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 ...

The Interaction between the Sheet/Tool Surface Texture and the Friction/Galling Behaviour on Aluminium Deep Drawing Operations
(MDPI, 2021)
The increasing demands for lightweight design in the transport industry have led to an extensive use of lightweight materials such as aluminium alloys. The forming of aluminium sheets however presents significant challenges ...
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 ...
Influence of the pressure dependent coefficient of friction on deep drawing springback predictions
(Elsevier Ltd., 2016)
The aim of this work is to show the influence of defining a pressure dependent friction coefficient onnumerical springback predictions of a DX54D mild steel, a HSLA380 and a DP780 high strength steel. Thepressure dependent ...
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
(Springer, 2021)
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 ...
