| Abstract Scope |
In the recent years the determination of non-proportional loading paths has been in the focus of many publications. Different models for the prediction of necking after non-proportional loading paths have been published and validated. Lately also a change in loading direction has been investigated. It was found out, that next to the deformation history, a change in loading direction leads to different Forming Limit Curves (FLC). The aim of this paper is the characterization of the influence on the mechanical parameters in the tensile test. Pre-formed tensile tests with and without a change in loading direction under different temperatures are investigated in order to determine the influences on a micro-alloyed steel and an aluminum alloy. Next to those parameters, the fracture surfaces are studied to assess the different fracture modes. These results contribute to a better understanding of the anisotropic hardening effects and the different fracture modes. |
