Biaxial tester

The Biaxial tester loads a sheet metal specimen on arbitrary tension and/or simple shear deformation. With this equipment the hardening behavior of metal can be investigated under multiaxial loading conditions. The deformation is recorded with a camera and forces in the tension and shear direction are logged with LabVIEW, approximately 40 data points per second. Stress–strain curves are easily determined in the post processing. Strain rates up to 0.5 s-1 are possible. Besides, an algorithm is available to control the strain path real-time. The temperature and magnetic response can also be measured during a test.
