Third party funded individual grant

Project details
Short description
The aim of the research project is the analyzation of the relevance of the kinematic hardening in the numerical design of sheet metal forming operations with closed profiles. By using standardized tests, such as the uniaxial tensile test or the tension-compression test with extended evaluation, as well as an influence analysis of different tool geometries, the kinematic hardening is quantified on both the material and the workpiece side. With the creation of a stress based indicator for predicting the load directional material behavior, a parameter for the post-processing of the numerical simulation should be further developed to identify critical points in the computer aided component design.
This project is in cooperation with Chair of Forming Processes of TU Dresden.
