Device For Cupping Experiments

This supplement to the universal material tester enables deep-drawing and cupping experiments to be performed to assess the material properties of thin sheet. A mirror permits the underside of the specimen to be observed and thus makes it possible to see exactly how cracking starts. The deep-drawing conditions are similar to those used in practice. A sheet specimen is clamped between the die and the holder. The specimen is then deformed using a spherical punch until it cracks. Using these device thin sheets up to thickness of 2mm can be investigated.
