Abstract

Change of strain path is a familiar phenomenon during continuous stamping operations of sheet metal for several applications, including automotive body parts. Strain path transition can potentially alter the forming limit of the material. Controlling the strain path change in a single deformation stage is a key challenge in elucidating this strain path-dependent deformation. In this work, a novel testing rig and specimen geometry that is capable of changing the strain path of a sample continuously without unloading the specimen were conceptualised, modelled, and subsequently manufactured. The size of this mechanical test rig permits it to be placed inside a scanning electron microscope (SEM) chamber in order to study strain path transition in situ to highlight strain localisation and related microstructural changes in real time. Using this apparatus, the effect of strain path change on material microstructure was investigated by carrying out in situ SEM and electron back-scattered diffraction (EBSD) analysis.
