Kurzbeschreibung (Abstract)
The aluminum alloy EN AW-7075 T6 is used in the automotive sector for itsfavorable strength-to-weight ratio. However, the limited cold formability is currentlyaddressed by energy- and time-consuming temperature-assisted processes. In orderto limit the effort to critical forming areas only, the state-of-the-art shows promisingresults for increasing the blank temperature in the range of warm forming. Thedesign of new processes in an industrial context requires appropriate numericalsimulation with inherent complexity due to time- and temperature-dependenteffects. Herein, the potential of a newly developed tool setup and process chain withintegrated local contact heating of the EN AW-7075 T6 blank is investigated on thebasis of a curved hat profile. A thermomechanically coupled FE model of the processis developed and validated. The influence of the local heating layout is analyzed inexperimental forming tests and a corresponding process window is derived. Theinfluence of local heating on the occurring failure mechanisms is discussed basedon simulation results. The equivalent plastic strain evolution is successfully used toevaluate the local heating dependent failure behavior. A significant increase in theoverall formability of the part is achieved by the proposed process chain.
