A Method for suppresion of defects in zigzag bending of sheet metal
(CIMNE, 2015)
Conference report
Open AccessThis study presents methods for suppression of defects observed in zigzag bending of sheet-metal or plate. This type of bending is widely used in industry for manufacturing structural parts in automobiles. Although it is ... -
Advanced material model for shear cutting of metal sheets
(CIMNE, 2015)
Conference report
Open AccessA finite-element simulation of the shear cutting process is used to predict thegeometry of the cutting surface. A fully-coupled Lemaitre-type model is used in the process model for the description of the material behaviour. ... -

FLSD as a good choice in sheet forming of AHSS
(Dassault Systèmes, 2011)
Conference report
Open AccessThe automotive industry has increased significantly the use of advanced high strength steels (AHSS) in many structural components, with the aim to reduce weight and also to increase safety. The high resistance of these ... -
Fundamental FEM analysis on tensile deformation of the sheet metal embossed on both sides of the plane
(CIMNE, 2015)
Conference report
Open AccessIn this study, the tensile test of the embossed sheet was conducted and the tensile deformation behavior is experimentally investigated. Also, in this study, the finite-element method (FEM) analysis on tensile deformation ... -
Microstructural evolution and mechanical behavior of an Al-6061 alloy processed by repetitive corrugation and straightening
(Multidisciplinary Digital Publishing Institute (MDPI), 2020-04)
Article
Open AccessThe repetitive corrugation and straightening process is a severe plastic deformation technique that is particularly suited to process metallic sheets. With this technique, it is possible to develop nano/ultrafine-grained ... -
Numerical analysis of forming sheet panels with stiffening ribs
(CIMNE, 2015)
Conference report
Open AccessThe transport industry, especially aviation, pays special attention to vehicle weight because lower weight means lower fuel consumption and in turn lower environmental pollution. Not only light metals like aluminium and ... -
Optimization strategies and statistical analysis for springback compensation in sheet metal forming
(CIMNE, 2015)
Conference lecture
Open AccessGeometrical in accuracies of sheet metal parts due to springback are one of the main sources of lack of dimensional accuracy. Therefore, when designing a process to obtain a piece,it is mandatory to take in to consideration ... -
