Cupping Experiment
- The penetrator is made of hardened steel, the cupping specimen is clamped between the clamping plate and the die plate.
- An angled mirror is placed below the die plate to enable easy viewing of the specimen rupturing.
- As more pressure is applied, the cup forms until it ruptures as seen in the angled mirror.
- The penetrator sphere is first lubricated then using the Universal Testing Machine it is pressed into the cupping specimen causing a cupped shape indentation to form.
