| Abstract Scope |
Although George Quinn did not have a formal role in the development of the sectored flexural strength and rotational flexural strength test methods, George’s storied body of work and his personal commentary influenced their developments. The sectored flexural strength test measures axial tensile failure stress of brittle material cylinders and tubes and enables harvesting of multiple specimens and generation of multiple data points out of a cylinder or tube. The rotational flexure strength testing of a whole cylinder or tube superimposes continuous rotation and monotonically increasing flexure and, in principle, will desirably cause fracture to occur from the largest strength-limiting flaw on the circumference. This presentation reviews both methods, shows examples, their efficiencies, and discusses imposed effective sizes pertaining to strength-size-scaling as well as other considerations.
