Dec 20, 2017 · The application of finite element analysis has been presented in multiscale metal forming process. A 3D finite element method (FEM) has first been proposed to analyze the deformation mechanism of thin strip cold rolling with the consideration of friction variation in deformation zone. The crystal plasticity finite element method (CPFEM) is applied on the simulation of surface asperity Aspects of ductile fracture and adaptive mesh refinement Dongxi Lv, Yuanming Zhang, Numerical simulation of chipping formation process with smooth particle hydrodynamic (SPH) method for Cai Zheng, Damage modelling in metal forming problems using an implicit non-local gradient model L.

Process modelling at SINTEF is based on advanced mathematical modeling and simulation tools combined with our well-equipped laboratories and experimental facilities. Our research stretches from understanding and modeling of multiphase systems, material mechanics, manufacturing processes, to process design and optimization and industrial implementation. The Numerical Simulation of Multi-Stage Sheet Metal Bauschinger effect is significant for metal forming, particularly for aluminum. A material constitutive model especially for multi-stage sheet metal forming is presented in this paper, which is improved based on Yoshida-Uemori(Y-U) model assumes that there exists different coefficient on equivalent back stress and boundary surface between stages.Numerical Modelling of Metal Forming by SPH with Multi Numerical Modelling of Metal Forming by SPH with Multi-GPU Acceleration Large material distortion, plastic deformation and forging make the numerical modelling of metal forming a difficult task. Grid-based methods such as the Finite Element Method (FEM) are incapable of simulating this process as these schemes suffer from mesh distortion and mesh entanglement.
