). A novel approach to investigate surface roughness evolution in asymmetric rolling based on three dimensional real surface. Finite Elements in Analysis and Design, 74 (October), 1-8.A novel approach to investigate surface roughness evolution in asymmetric rolling based on three dimensional real surface AbstractSurface roughness affects the friction behaviour, stress distribution and surface quality; moreover this influence is more significant when scaling down the strip size. A novel approach has been proposed to investigate the surface roughness in asymmetric rolling based on Finite Element Analysis (FEA). Evolution of asperity flattening, contact area ratio and surface roughness is investigated under various simulation rolling conditions. The model reviewed numerical solutions for real surfaces with asperities of arbitrary shape and varying size and height distributions. The rolling characterization has also been identified for asymmetric rolling. The difference of change in surface roughness for upper and lower strip surface is large during rolling. The effect of the speed asymmetry factor on strip bending has been established. An increase of the speed asymmetry factor causes an increase in the strip curvature, while the force parameters decrease with increasing asymmetry factor. The speed asymmetric factor influences the strip bending significantly. It is the first attempt to carry out this kind of research in surface roughness based on real surface during asymmetric rolling of thin strip.

“…Several studies have shown that the quality of the rolling process depends on different parameters: roll radius ratio, roll speed ratio, workpiece-roll friction coefficient ratio... [2,14,51,53]. This studies have generally an interest on the influence of those parameters on the reduction of the rolling force and the deflection of the piece at the exit.…”

A micromechanical ductile fracture model, extended to take account thermal heating due to mechanical dissipation within the material, is used to study a 3D-asymmetric rolling operation. The void coalescence mechanism by intervoid material ligament necking is also considered by using an extension of the Thomason's criteria. This formulation is implemented into ABAQUS/Explicit finite element package and applied to simulate the effects of some rolling parameters on the evolution of the voids volume fraction and voids shape of a A1050P aluminum. The confrontation with available experimental results shows the capability of this constitutive law to predict the rolling force variation for different reductions. The results show, on one hand, that optimum parameters could be found in order to reduce the rolling force and, on the other hand, that rolling parameters exert an influence on the final microstructure of the rolled metal.

“…For the precise control of warping during flat rolling of bimetallic slab, the prediction of warping amount at given rolling condition is essentially required. Analyses have been conducted with particular emphasis on FEM [18][19][20]. The results generated by finite element analysis should be more readily accessible, less costly, or more complete than can be obtained by laboratory experiments or tests during actual manufacturing.…”

The mismatch of lengthwise elongation due to the difference of deformation resistances between constituent materials of bimetallic slab can cause warping. As the warping of bimetallic slab can lead to poor product shape with reduced productivity, this study focuses on the effect of differential speed rolling on the reduction of warping. The effects of differential speed rolling on the reduction of curvature are mainly performed by FEM based on fundamental processing parameters. Differential speed rolling experiments by using low-weight Al1050/Al6061 bimetallic slab produced by continuous clad casting have also been performed for the validation purpose. As rolling experiments for numerous processing conditions are hard to achieve, limited number of experiments has been performed in this study. Simulation results based on parametric study provide a broad overview on the warping behavior in Al1050/Al6061 bimetallic slab rolling.
