Numerical Models for Predicting Spring-back of Stamped Titanium Alloy

Popis výsledku v původním jazyce

The paper is focused on the definition of a suitable material model of the titanium alloy, which is subsequent used for the numerical simulation of drawing process and the material spring-back by the FEM. Simulation of drawing process and subsequent spring-back was done in the environment of the simulation software PAM-STAMP 2G. In this simulation were used material models as Hill 48 and Vegter. These material models were defined in a version with isotropic and kinematic (Yoshida model) hardening of material. For a definition of these models, there was necessary to know the individual characteristics of material. Needed material characteristics were determined by the selected material tests. Results obtained by numerical simulations were compared with the results that have been measured by the real experiment of own stamping production.
