Numerical and experimental investigations of the nickel thin sheets micro-deep drawing process

Abstract

The increasing demands for small devices which have multiple applications in automotive industry, in chemical industry but also in medicine leads to new approaches concerning both the simulation and the experimental analysis of the material forming processes. In this paper are presented the experimental and numerical studies regarding the micro-deep drawing of Ni (99.999%) sheets. For experimental point of view the influence of punch and die radius toward the level of forces and parts quality was investigated. A numerical study was performed in order to analyse the deformation process. The obtained numerical results were validated by the experimental work.
