Scratch Test as a Fracture Process
The scratch test consists in pushing a hard probe across the surface of a softer material. Dating pack to the pre-Hellenic area and the Mohs scale, the scratch test is one of the oldest mechanics-of-materials tests; however, the underlying mechanics are not fully understood. The research objective is to formulate a fracture mechanics model to correlate the forces and depth measurements during scratch testing to intrinsic material fracture characteristics.
