Abstract:
This paper deals with mathematical modeling of one of the effective technologies of plastic metal forming – multistep cold metal forging. Experimental results are given on the plastic behavior of metals under cyclic loading at large strains accumulated for one cycle. Based on the experimental data obtained, a plasticity model is developed and shown to be effective in testing and improving the technology of forging a nut blank by using a computer-aided engineering analysis system.
Keywords:
plasticity, cyclic deformation, plastic metal working, computer system of the engineering analysis.
