Determination of the temperature development in the cryogenic range for determination of heat transfer coefficient
(Technische Universität Dresden, 2023)Lightweight materials such as aluminum alloys have an important role to play in weight reduction. However, their limited formability at room temperature poses a major challenge and restricts their use. Significant improvements ... -
Forming and cutting at high strain rates Part 1: Experimental data and FE-model for an inverse material characterization of DC06 at high strain rates
(Technische Universität DresdenFraunhofer Institute for Machine Tools and Forming Technology IWU, 2023)High-speed processes can lead to significant technological advantages like an increased formability, reduced springback or an improved quality of cutting edges. For conventional forming processes, quasi-static conditions ... -
Forming at high strain rates Part 2: Analysis of adiabatic heating based on tensile tests of DC06
(Technische Universität DresdenFraunhofer Institute for Machine Tools and Forming Technology IWU, 2023)In high strain rate forming processes two superposing and opposing effects influence the flow stress of the material: strain rate hardening and thermal softening due to adiabatic heating. The presented FE-model and ... -
