Abstract

Determination of flow curves of metals, which are indispensable for numerical simulations of forming processes, is often limited to tensile or compression tests. However in some cases the shear stress-strain behavior of materials needs to be determined as well. In the paper digital analyses of shear-hat test at room temperature were performed for various steels, AlMg₃ aluminium alloy and AZ80 magnesium alloy. Comparative analyses of process parameters and specimen geometry as a function of tool displacement were performed for better understanding of the testing procedure.
