The Fea Simulation Of Stainless Clad Strip In Cool-Rolled Pdrocess

The manufacture craft of stainless clad strip which is belong to bimetal composite plate is carried out in this paper, and the cool-rolled process of stainless clad strip is simulated using the large finite-element software ANSYS.The numerical simulation of the rolling process is studying emphasis in the lab of rolling field. The finite-element code ANSYS that is emerging with development of computer industry can be suitable for solving the large contact and highly non-linear question. Because of the complex model of stainless clad strip, great lots of plotted elements and the non-linear material, there are many very complexity questions of plasticity fluent in the cool-rolled process, and stress-strain near the interface of stainless clad strip is also very complexity varieties. With suitable conditional hypotheses and interface condition of stainless clad strip, the three-dimensional and two-dimensional finite-element model including rollers and rolled plates are established in simulation. Using suitable loading and edge-restraint conditions, the distribution of equivalent stress and equivalent can be obtained in the rolling deformation field, and the three-dimensional distribution of rolling force of stainless clad strip is also obtained, so reduction of stainless clad strip is established in first rolling pass. These simulation results are in agreement with the experimental results during stainless clad strip produce in the cool-rolled workshop. Edge crack of stainless clad strip in cool-rolled process is also analyzed, and is also calculated the edge crack opening displacement with different cool-rolled reduction.It has been developed many years using FEM methods to simulate rolling process. But the simulation of stainless clad strip is still infrequence, Therefore, the study by use of finite-element software ANSYS to simulate cool-rolled process of stainless clad in this article is bring forth certain new ideas.
