Impact of shock-wave loading regimes on structural and elastic characteristics of a single-component abrasive tool

摘要

The article considers the issues of determining the elastic characteristics of a single-component abrasive tool depending on the porosity of the abrasive tool after pressing the abrasive compound studied; the method of determining the modulus of elongation and porosity based on theoretical and experimental data has been used; the dependency graph between the modulus of elongation and porosity, as well as experimental formulas reflecting these dependencies are presented. Based on the experimental and calculated data on the density, porosity and the size of the modulus of elongation, depending on the pressure of the shock wave during pressing and the initial aluminium oxide grains sizes, empirical dependences of elastic characteristics have been determined in order to predict the production of a single-component abrasive tool without a bond with predetermined properties.
