Summary

Weiler showed in 1987 that the strength of ceramic heat exchanger tubes could be evaluated by flexural strength tests of cylindrical segments or longitudinal slices cut from the tubes. In the present study, a similar approach has been applied to measure the strength of short solid ceramic cylinders. Large loads are normally needed to break these cylinders in flexure and there is a risk of contact stress problems at the loading points. A simple remedy is to cut the rods longitudinally into two halves and test each half. Split zirconia short rods were tested using a conventional bend fixture with simple modifications. Strengths were compared to those of solid round rod parts. Fracture origins were the same type in each case. The split cylinder or segmented cylinder method is a simple, practical, and effective way to measure flexural strength.
