The effects of sample size and padding material on the results obtained from the diametral compression test are presented and discussed. A series of uniform alumina samples ranging from 6.35 mm in diameter and 3.175 mm long to 12.70 mm in diameter and 12.70 mm long were tested. Tests were conducted using Cu, Al, Pb and polystyrene pads, IBM cards and no pads. The results show that the fracture strength of the samples depends on sample size and the padding material used. Tests were also conducted on simulated nuclear waste forms. The first direct observation of the initiation of secondary cracks in the triple-cleft fracture mode is reported.
