Device for Cupping Experiments

Model HV-EXP2546
Technical Description This supplement to the universal material tester enables deep-drawing and cupping experiments to be performed to assess the material properties of thin sheet. 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. A mirror permits the underside of the specimen to be observed and thus makes it possible to see exactly how cracking starts. Using this device thin sheets up to thickness of 2mm can be investigated..
