Analysis of the mechanical and microstructural fluctuations of high-strength steels and their effect on bending angle
Muñiz García, Laura; Trinidad Naranjo, Javier; GALDOS, Lander (MDPI, 2023)The quality and complexity demands of manufactured parts in sectors such as automotive and aeronautics lead to narrower process windows. This affects the repeatability and stability of the process, where material properties ... -
Friction Modelling for Tube Hydroforming Processes : A Numerical and Experimental Study with Different Viscosity Lubricants
GALDOS, Lander; Trinidad Naranjo, Javier; Otegi, Nagore; García-Crespo, Carlos (MDPI, 2022)The final quality of sheet and tube metal–formed components strongly depends on the tribology and friction conditions between the tools and the material to be formed. Furthermore, it has been recently demonstrated that ... -
The influence of the kinematic hardening on the FEM simulation of Tension Levelling Process
Garcia, Aitor; Trinidad Naranjo, Javier; Otegi, Nagore; Mendiguren, Joseba; Sáenz de Argandoña, Eneko; GALDOS, Lander (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 ... -
Sensitivity Analysis of Near Solidus Forming (NSF) Process with Digital Twin Using Taguchi Approach
Sajjad, Muhammad; Trinidad Naranjo, Javier; Plata, Gorka; Lozares, Jokin; Mendiguren, Joseba (Springer Nature, 2024)Forging at near solidus material state takes advantage of the high ductility of the material at the semi solid or soft-solid state while keeping most of the mechanical properties of a forged part. The technology is at ... -
Substitutive Press-Bolster and Press-Ram Models for the Virtual Estimation of Stamping-Tool Cambering
Abbasi, Farshad; Trinidad Naranjo, Javier; Otegi, Nagore; Sáenz de Argandoña, Eneko; GALDOS, Lander (MDPI, 2021)Today’s stamping simulations are realized by ignoring the elastic deformation of the press and tooling system through the assumption of a rigid behavior and a perfect press stroke. However, in reality, the press and tool ...
