A numerical strategy based on the finite element method and intended for an
accurate analysis of the scratch test is presented. For simplicity, but not out of
necessity, the material was described by classical von Mises elastoplasticity
utilizing large deformation theory. Based on this strategy numerous results
are presented and correlation of scratch properties is discussed within the
framework of theory for indentation testing. Furthermore, the existence of a
representative plastic strain in the spirit of Tabor was studied. The investigation also
concerns details regarding frictional effects, normal vs. tangential scratch
hardness, similarities and differences between indentation and scratch test
characteristics as well as details regarding the behavior of local field variables at
scratching.
