LS-DYNA in Metal Forming. The main application of LS-DYNA in metal forming is sheet metal stamping. The incremental approach of LS-DYNA allows users to simulate multi-stage sheet metal stamping processes with high accuracy. Using the implemented multiple core technology the simulation time can be very short.

Modeling and numerical simulation of multi-gripper

Apr 15, 2014 · Multi-gripper flexible stretch forming (MGFSF) is a recent technological innovation of sheet metal forming process. Straight jaws in traditional stretch forming machines are substituted for a pair of opposed clamping mechanisms movable relative to each other during the forming process. In this paper, spherical part is selected as the study object, and numerical simulations of the MGFSF Modelling highly deformable metal extrusion using SPHModelling of extrusion and similar metal forming processes model was assumed for the numerical simulations. The real ability of SPH to model metal extrusion in a 3D geometry Numerical Modelling - an overview ScienceDirect TopicsNumerical modelling of rock metamorphic process is a very useful and important tool in the field of geological and geochemical modelling. Through this kind of modelling work, not only can the rock metamorphic process be better understood, but also the ore body forming

Numerical Modelling Of Metal Flow In The Cold Forming

May 25, 2007 · The forming processes for two industrial coldformed fasteners are examined. The first is a tubular component formed into a tophat shape during a singlestage operation. The second is an axisymmetric stepped rivet formed in a multistage process. In each case the deformation of the workpiece is modelled using an elasticplastic finiteelement method, to indicate how Numerical Modelling Of Metal Flow In The Cold Forming May 25, 2007 · The forming processes for two industrial coldformed fasteners are examined.

Special Issue "Modelling and Simulation of Sheet Metal

The aim of this Special Issue is to collect full papers, communications and reviews, about modeling and numerical simulation of sheet metal forming processes, which may contribute to bridge the gap between dream and virtual reality. Prof. Marta Oliveira Prof. José Valdemar Fernandes Guest Editors. Manuscript Submission Information Special Issue "Numerical Modelling and Simulation of Metal The numerical simulation of metal processing, coupled with the modelling of the structural evolution allows to reduce time and cost expensive tests at lab and industrial scale. Here, multi-scale modelling is an appropriate means to describe the development of the nano, micro and macro structure and, hence, to determine the local materials Thesis title:Numerical modeling of sheet metal forming Hydrodynamics" (SSPH) for the numerical modeling of sheet metal forming processes, namely stamping and hydroforming. The numerical developments in the framework of the PhD thesis will concern the review and alleviation of numerical locking phenomena encountered in the classical SPH method such as non-consistency and instability in tension.

Numerical simulation of powder metal forming process

The method of Smoothed Particle Hydrodynamics (SPH) is used for the numerical simulation of compaction of iron powder. The character of SPH allows for accurately tracking relevant material properties within a Lagrangian coordinate system without the problems due to limited mesh deformation allowed by the fixed connectivity of the Finite Element Method (FEM).
