A model of the indentation using conical and pyramidal indenters has been proposed, in which not only a sample but the indenter as well are elastoplastically deformed and their materials obey the Mises yield condition. These conditions are characteri

Ductile mode cutting has become an emerging technology of machining silicon, where the originally brittle material is removed by a plastic flow of the phase-transformed material, yielding ductile chips, thus leaving a crack-free smooth surface. Howev

The deformation of metallic glasses (MG) may be considered on the basis of three models: the STZ (shear transformation zone) model; the free-volume model; and dislocation plastic flow. For the example of MG on the iron base, it is shown that dislocat
