The mini biaxial tensile machine allows one to apply in-plane biaxial stress states with arbitrary stress ratios and to perform strain path changes on thin-sheet metals. The device is optimized for in situ usage inside a scanning electron microscope and at synchrotron beam lines. Both dogbone and cruciform shaped samples can be mounted. The machine is controlled by an in-house written LabVIEW steering program.
