Suggested Methods for Determining Hardness & Abrasiveness

Vickers [11] tests determine the microhardness of indi- vidual rock minerals. A pyramidal-shaped diamond is applied to the surface with a specified force. The area of the permanent residual deformation divided by the applied force is a measure of the hardness. The Knoop test has the ability to determine directional hardness of crystals.

Modeling of extrinsic defects in silica fibers using

Vickers indentation has been used to introduce controlled flaws in fused silica optical fiber in order to model the behavior of 'weak' defects encountered in practice. Novel techniques are used in order to conveniently examine indentations over a broad range of residual strength; these include the use of flat fiber which facilitates specimen alignment during indentation and
