there is a complicated relation between cold flat rolling parameters such as effective input parameters of cold rolling, output cold rolling force and exit thickness of strips. in many mathematical models, the effect of some cold rolling parameters has been ignored and the outputs have not a desirable accuracy. in the other hand, there is a special relation among input thickness of strips, the ...

Numerical simulation of the deformation process during flat rolling of multifilament HTS tapes has been investigated using a commercial FEM program, ELFEN. The numerical models were built up in 2D and 3D using a DruckerPragerKap model for the powder. Three different roll diameters (024 mm, 0 8 5 mm and 0126 mm) have been investigated. It is found that it is possible to perform numerical simulat...

In this research a final element model for simulating three dimensional deformation in rolling of flat product is modeling in ABAQUS and further developed to study the frictional effects on spread and bulge. To predict the magnitude of bulging , the rolling process is approximated by successive forging steps. The elongation or the average spread at each step from the previous calculations are u...

In this research, flat rolling process of bonded sandwich sheets is investigated by the method of upper bound. A kinematically admissible velocity field is developed for a single layer sheet and is extended into the rolling of the symmetrical sandwich sheets. The internal, shear and frictional power terms are derived and they are used in the upper bound model. Through the analysis, the rolling ...

In this paper we are interested in the dynamics and numerical treatment of a rolling disk on a flat support. The objective of the paper is to develop a numerical model which is able to simulate the dynamics of a rolling disk taking into account frictional resistance against sliding, pivoting and rolling. A mechanical model of a rolling disk is presented in the framework of Non-smooth Dynamics. ...
