| The indenter is mounted on a Del-Tron air-bearing stage and this indenter assembly is moved in the vertical direction using a Parker Daedal Cross Roller Bearing stage. |
| The mean pressure between the surface of the indenter and the indentation is equal to the load divided by the projected area of the indentation. |
| The Shore seleroscope, which is the commonest example of a dynamic-hardness tester, measures the hardness in terms of the height of rebound of the indenter. |
| A large degree of hysteresis upon indenter retraction was observed. |
| The indenter is joined to a bending beam that measures the force applied by a pair of transducers. |
| The indenter was secured into the arbor of a milling machine. |
