NUMERICAL INVESTIGATION ON COPPER CLADDING ON ROLLING PROCESS TO DETERMINE EFFECT OF STRESSES ON DIFFERENT TIME PERIOD

Mechanical engg

A finite element model of the rolling processes for nonlinear Copper alloy has been developed for I-section flat rolling stock with rectangular cross section. This model can be used to analyze the flat rolling of Cladded Copper Alloy rectangular strips under a series of different parameters, providing the rolling designer with a tool that he can use to understand the behavior of the copper as it flows through the different passes. The models developed, take into account all of the non-linearity present in the rolling problem: material, geometric, boundary, and heat transfer. A coupled thermal-mechanical analysis approach is used to account for the coupling between the mechanical and thermal phenomena. The model predicts the equivalent
