Analysis of the scratch test for cohesive-frictional materials
… analytical solutions for the relations between scratch hardness and strength properties of cohesive-frictional materials of the Mohr-Coulomb and Drucker-Prager type. Based on the lower-bound yield design approach, closed form solutions are derived for frictionless scratch devices, and validated …

Characteristics and modeling of the fracture properties of polymer-silica microparticulate composites via macroscopic scratch tests
… inclusions is developed as a model material. The hardness and fracture toughness of composites containing 0%, 5%, 10%, and 20% spherical glass bead inclusions by volume are analyzed using a built-in- house macroscopic scratch test device. The elastic modulus and compressive strength are obtained …

Nanoindentation Under Dynamic Conditions
… transformation temperature. Multiple impact and scratch indentation are two modes of indentation which are thought to approximate erosive and abrasive wear mechanisms, respectively. These were utilised to investigate the wear resistance of several novel coatings formed by plasma electrolytic …
