FIELD: material testing. SUBSTANCE: in compliance with proposed method plastic bulge is formed by impact of striker with spherical butt along normal to surface of tested specimen. Ratio of formation of thickness in vertex of bulge to velocity of impact is assumed as measure of defomability found by formula ξ=(1-h/h)/v,, where his thickness in vertex of bulge; h is original thickness; v is velocity of impact. EFFECT: expanded field of application of proposed method for evaluation of deformability of material under local squeezing-out, reduced expenditures on its realization. 1 cl, 2 dwg |
