Investigation of Elasticity and Strength of Ceramics Subjected to Tensile and Compressive Loads.

Abstract

Experimental work was performed to verify the previous theoretical analysis of the effect of ellipticity on the nominal tensile strength of internally pressurized ring test specimens. Two test materials, Plexiglas and ATJ graphite, were used. In terms of strength, Plexiglas shows no effect of ellipticity over the range (0% - 5%) investigated. Results obtained on graphite show a large effect of ellipticity on strength, although this effect is less than that predicted by theory. Results obtained in a photoelastic study of strain concentrations at low stress levels in specimens having 0% to 5% ellipticity are in agreement with theoretical predictions.
