BIAXIAL FLEXURE TESTS FOR CERAMICS.

Abstract

Three loading schemes that produce biaxial tension in flat-plate specimens were evaluated to determine the suitability of each for strength-testing of ceramics. The analyses were made in connection with an on-going study of multiaxial stress effects on ceramic strengths. The three biaxial flexure tests evaluated were: ball-on-ring, piston-on-3-ball, and ring-on-ring. Only the ball-on-ring loading was satisfactory; uncertainties exist about fracture stresses in the other two cases.
