Microforming analysis of 304 stainless steel with several grains across the section

Abstract

Thickness of the metal material reaches micron level, its mechanical properties show a certain size effect. The cupping test can evaluate the forming performance of thin metal sheet. In this paper, ultra-thin 304 stainless steel with the thicknesses of 0.03 mm, 0.06 mm and 0.1 mm is selected as the test materials. The forming performance is studied through test. Simulation analysis is also established to investigate the influence of parameters on the forming performance.
