Popis:	Factors in obtaining and interpreting tensile data on ceramic bodies are discussed, with particular attention given to the use of bending. A bend test can be used conveniently to obtain precise tensile data as long as stress is directly proportional to strain in both tension and compression. The moduli of elasticity in tension and in compression need not be equal. To account for any such inequality, strain in both bottom and top longitudinal fibers should be considered in computing the tensile stress. Extraneous stresses in bending can be essentially eliminated through proper specimen design and manner of loading. Details for the consideration of extraneous stresses in practice are presented, along with an equation for computing tensile stress precisely from bend-test data. Limited experimental work on oxide-base and silicate-base bodies supported the theoretical analysis of bending and indicated the suitability of a refined bend test for precise ceramic work.
