Four successful 21 biaxial compression tests were performed on Wesgo AL-995 alumina. The average strength measured was 572,000 psi with very little scatter standard deviation 7 ksi in the data. This value is 28 greater than the greatest uniaxial strength reported for this material. A testing technique was developed which minimizes the damage done to the specimen on fracture, permitting subsequent examination of the fractured material. The design and fabrication of a 11 biaxial compression test device is described. Preliminary tests performed with this device indicate that it has a good probability of being capable of breaking the test specimen in the desired stress state. Author
