Effect of High Pressure on Dynamic Compressive Strength of A95 Alumina Ceramics

Abstract:

The dynamic strength expressions of materials were reviewed in case of one-dimensional strain shock loadings in this paper, the effects on the strength were suggested to be considered of hydrostatic pressure and high strain rate. A modified form for the Hugoniot Elastic Limits was given associated with the Drucker-Prager yield criterion, the effect of hydrostatic pressure being included. Free surface velocity histories of particle were measured by VISAR system in plate impact experiments on alumina with a Light Gas Gun. The experimental determination of dynamic strengths of alumina was discussed and the open problems were clarified. By comparing the strength expressions of ceramic materials with the experimental results, the evident differences were pointed out. Their analysis and discussion were further given for the experimental phenomenon.
