An Experimental Study on the Compressive Biaxial Strength of Ceramics

Abstract

The factors in the testing of very brittle materials which can prevent the true strength from being realized are identified. An externally pressurized, closed end, cylindrical specimen is used to attain 2:1 biaxial compression. The first of a series of planned tests has been performed and 585, 000 psi was measured for the 2:1 biaxial compressive strength of an alumina. This is 31% higher than the uniaxial compressive strength. A description of the testing equipment is given. Two analyses are presented. One deals with the buckling characteristics of the test specimen. The other presents the compliance analysis used to design a 1:1 prestressing fixture.
