Device For Cupping Experiments

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.
