Numerical and Analytical Investigation of the Sandwich sheet Rolling Process ConsideringCoulomb Friction
Sandwich sheet rolling process is investigated using an analytical method (slab method) and a numerical method (finite element method). The horizontal stress distribution in the layers, the rolling pressure along the contact interface and the neutral point between the roll and the sheet are investigated. Then the affects of the parameters such as the friction between the sheet and the roll, shear yield stress ratio of the matrix and clad layers, front and back tensions on the rolling characteristics such as the pressure and neutral point position are studied. The results demonstrate that the finite element method results are very near to the slab method resultsand extra simplifying assumptions in the slab method cause low deviance in the results. In both methods As the friction coefficient increases, the rolling pressure increases and the neutral point nears the entrance of the roll gap. As the shear yield stress ratio increases, the rolling pressure increases but the neutral point doesn’t transmitted. As the front or back tensions is applied on the sandwich sheet, the rolling pressure decreases and the neutral point transmitted inverse of the tension direction.
