The paper gives the results of experimental study of the regularities of damage in such brittle materials as glass and ceramics at local loading by the methods of sample surface scraping by Rockwell indenter up to chipping out. Hardness values at scraping of the studied brittle materials were determined. It is shown that hardness at scraping is higher than the hardness values at indentation with a standard sharp indenter, mostly by 20%. Dependencies of surface damage on load, as well as those between hardness at scraping, damage, modulus of elasticity and critical stress intensity factor, are presented. A method of application of experimental diagrams of brittle material damage for reliable determination of the degree of their local fracture, depending on the stress level is proposed. 23 Ref., 2 Tabl., 5 Fig.
