Abstract

This article concerns the forming of a steel thin-wall short-tube by an innovative small surface contact deformation process. A Finite Element model was built to predict the forming of the workpiece. The model controls the complex kinematics of the process. The problems associated with contact control and computation time are also investigated. Compared with measurements taken by the industrial partner, the first results obtained are highly promising, with regard to predicting both the workpiece geometry and the forces acting on the tools.

Abstract

This paper introduces the application of micro-deep drawing of single and multicrystals of aluminium in order to identify parameters of micro-mechanical models. The information obtained experimentally is abundant: load-displacement curves of the punch, the evolution of grain orientation, mapping deformations throughout the test. All this experimental data was used to validate the multiscale models introduced in a finite element code for loading paths ranging from biaxial tensile to simple tensile. [ABSTRACT FROM AUTHOR]
