Numerical modelling of thermomechanical processes related to bulk forming operations
A therir~oir~echanically sound, deco~ipled inodel, nunierically unified for cold and hot bulk metal forming is cast into a finite eleme7it fonttulalioii. Tlie irlechanical niodale is based on elasto(visco)plastic niaterial costztutive laws and general interface frictional contact conditions with the assumption of rigid tools. ~ntroductiolz of a logarithn~ic strain based finite strain iriodel in...
متن کاملFinite Element Modelling of Forging and Other Metal Forming Processes
The fundamental mechanical formulation is recalled for simulation of metal forming processes. The basic principles of 3-dimensional finite element discretization and of time integration are summarized. Several important numerical developments for efficient computation of large plastic deformation are briefly described. Various fields of applications to real processes are reviewed. Illustrative ...
متن کاملPrediction of Instability in Planar Anisotropic Sheet Metal Forming Processes
In this paper instability of planar anisotropic sheet metal during a few forming processes is investigated for the first time. For this reason components of the constitutive tangent tensor for planar anisotropic sheets are developed. By using the above tensor location of necking is predicted. Direction of the shear band is also predicted using the acoustic tensor. A finite element program is pr...
متن کاملInvestigation of the Forming Force in Torsion Extrusion Process of Aluminum Alloy 1050
In this paper, torsion extrusion (TE) process on 1050 aluminum alloy was investigated by simulation as a severe plastic deformation (SPD) method and the effects of friction coefficient, angular velocity of the rotating die and punch speed on maximum punch force were studied. A finite element (FE) model was developed to simulate the TE process via DEFORM software. The FE results were validated co...
متن کاملthe effects of atmospheric processes on tehran smog forming
air pollution is one of the most important problems in urban areas that always threaten citizen's health. photochemical smog is one of the main factors of air pollution in large cities like tehran. usually smog is not only a part of nature, but is being analyzed as an independent matter, which highly affects on the nature. it has been used as relationship between atmospheric elements such as te...
