Keywords:sheet metal, blanking, cutting surface, damage model, simulation. Abstract. A finite-element simulation of the shear cutting process is used to predict the geometry of the cutting surface. A fully-coupled Lemaitre-type model is used in the process model for the description of the material behaviour. The extended Lemaitre model
In recent years, some ductile fracture criteria, such as Cockcroft–Latham (C–L) criterion, Brozzo criterion, Oyane criterion, and Gurson–Tveergard–Needleman (GNT) criterion, have been proposed to analyze various material damage behaviors in the plastic deformation process. However, the first three criteria do not consider the effect of shear stress on ductile fracture, and the GNT

To improve the accuracy of forming simulations for sheet metal, the use of material models calibrated by multiaxial material tests is essential. Adequate material models can be calibrated on the basis of the contours of equal plastic work obtained by multiaxial material tests. However, because the tests often require special experimental equipment, they are not widely used by the
Abstract. True stress-strain values were obtained from tensile tests of 7075 aluminum, and by performing a finite element simulation analysis. The results revealed that various ductile fracture criteria resulted in different levels of accuracy in the simulation. Moreover, factors affecting ductile fractures, such as stress, strain, and damage

Herein, a three-dimensional (3D) finite element model of a strain clamp-conductor system is established, with an NY-300/40 compression-type strain clamp taken as an example. The tensile load-carrying capacity of the strain clamp under standard crimping conditions is analyzed with LS-DYNA software, and the simulation results are compared with the experimental results to verify the accuracy of
Metal sheets and thin-walled extrusions made of aluminum alloys may fail due to one or a combination of the following failure mechanisms (Hooputra et al. 2004): ductile failure due to nucleation, growth, and coalescence of voids; shear failure due to fracture within shear
Damage initiation. Metal sheets and thin-walled extrusions made of aluminum alloys may fail due to one or a combination of the following failure mechanisms (Hooputra et al. 2004): ductile failure due to nucleation, growth, and coalescence of voids; shear failure due to fracture within shear bands; and failure due to necking
The use of a dynamical constitutive model is essential for the numerical analysis of dynamic impact. In this study, uniaxial tension tests were conducted on aluminum alloy (AA) 6016-T6 sheets under different strain rates (0.001–100/s). The results show that the flow properties of AA 6016-T6 is slightly sensitive to strain
