- Abstract
This article examines the choice of the computer program DEFORM for finite-element analysis of transients in metal-shaping operations (MSO). The possibilities of the program for solving nonsteady problems that are fairly difficult to model are explored by using two different MSO as an example – forging on an AVS radial-forging machine with complex motion of the tool and the rolling of strip with the formation of fins on one side. The results of the solution are analyzed using the DEFORM post-processor. The availability of experimental data on the rolling of unilaterally finned strip and the forging of bars on AVS machines made it possible to evaluate the accuracy of the theoretical results. It is concluded that use of the DEFORM program is effective for studying transients in MSO. The data obtained in the process make it possible to design new and improve existing technologies and machines for shaping metals.
