- Abstract:
- The plastic deformation behavior of textured sheet metals under biaxial compression loading is mostly unknown, since the technical implementation of biaxial compression in experimental setups is challenging. Experimental data under biaxial compression loading of textured sheet metals may well be essential to describe their tension / compression asymmetry. There are yield criteria to account for this asymmetry, and for the Bauschinger effect – but accurate modeling relies on accurate experimental data. Various testing methods have been devised to complement conventional tensile testing. Yet there is no systematic work so far that describes the ‘third quadrant’ (σ-σ plane) under biaxial compressive loading. In this study, an experimental setup is presented that will help bridge this gap.
