Applied Physics and Mathematics Annotation << Back INFLUENCE OF PRESSURE ON IMPACT STRENGTH OF METALS AND ALLOYS L.S. VASIL’EV, I.L. LOMAEV In this paper, a theoretical study of the influence of compressive external hydrostatic loads on the dynamic properties and impact strength of plastically deformed metals and alloys at finite temperatures is carried out. Quantitative relations are obtained that make it possible to estimate the influence of pressure on the mobility of dislocations and the viscosity of a plastically deformable medium. Numerical data are presented showing a significant increase in the impact strength of metals at external pressures p ≥ 1 GPa. Keywords: Pressure, plasticity of metals, impact strength, destruction of metals. DOI: 10.25791/pfim.04.2023.1270 Pp. 57-64.
