Analytical model for strip-drawing
Source abstract
Abstract
A semi-analytical model which describes the process of strip-drawing is proposed. In this model the strip in tools is divided in three types of zones: unsupported arcs, zones of line contact and zones of distributed contact. In each zone the using of the force’s and the moment’s equilibrium with the relation between internal forces, moments and components of stress allows the determination of strain state and subsequently stress state in each point of sheet. For the correct modelling of hardening effect the step by step incremental plasticity was used and for the correct modelling of bending/reverse bending cyclic effect the mixed isotropic-kinematic hardening laws were implemented in the program code. At the output the program provides the deformed profile of sheet, stress and strain states of any point of the strip, thickness variation, internal forces and moment of each sheet element and the forces acting on each surface of the tools in contact with the strip.
