Numerical simulation of slab edging process by the Reproducing Kernel Particle Method considering friction effect

A mesh-free approach is used for analysing the effect of the friction factor on three-dimensional steady state slab edging, which is based on the Reproducing Kernel Particle Method (RKPM, Liu et al., 1995) and the material flow formulation for slightly compressible materials (Osakada et al., 1982). In order to cope with the singularity at the corner of the roll entry, a simple technique with a very thin array of cells at the inlet region adjacent to the plastic deformation zone (Xiong et al., 2003) is used. The results show that the dog-bone shape becomes smaller with the increment of friction factor. The roll separating force and total rolling torque increase with the friction factor.
