<![CDATA[There the outcomes concerning the investigations regarding floor energy then chasm durability on abrasive then other enormously strong substances the usage of the approach regarding micro stress so much affords high dosage about localization on the software over an external force action, are presented. The fundamental regularities over elastic-plastic deformation or brittle defeat of the procedure on micro indentation have been determined because of every the investigated materials. Based of the studies we additionally identified the power or energy conditions about elastic-plastic deformation and slight dud of the manner on micro indentation of fairly solid or brittle materials. It was once found, to that amount within the 1st flooring on the corrosion manner the precise work of break and the power depth element are immediately proportional after the bulk on the stress concentrator, i.e. the imprint diagonal. Therefore the power depth component so is widely used of mechanics or micromechanics concerning materials can keep legitimate solely when that is described among terms over sustainable increase concerning cracks of the 2nd board regarding unsound cleft of the investigated material. According in imitation of take a look at consequences we present the important traits regarding power then crack toughness on a quantity concerning abrasive substances ancient in enterprise or lookup organizations.Keywords: Method of micro pressure; Brittle fracture; Micro volumes; Origin; Critical stress; The relative elastic deformation.]]>
