Numerical Simulation for Metal Powder Cross Shear Rolling Compaction
Characteristics of cross shear rolling for metal powder roll compaction were analyzed. The finite deformation elasto-plastic constitutive model and corresponding calculation code were derived based on compressible continuum mechanics. Numerical simulations were performed for the cross shear rolling of metal powder. The rolling force development law under different compaction ratio and rolling speed ratio was studied. It showed that the rolling force decreased apparently as differential velocity ratio increased. Comparisons were done between simulations and experiments from references and the reliability of the mechanical models and calculation code derived in this paper were proved.
