Abstract

Models of formation of new surfaces in a firm body at stages of elastic and plastic deformations, the beginning and development of fragile destruction, destruction with existence of plastic deformation are presented. The assessment of the power expenses necessary for formation of unit of a new surface, and as influences on these expenses of plastic deformation is carried out. The method of determination of superficial energy of a material for fragile bodies is presented.
