Measuring Crack Length in Coarse Grain Ceramics
Source abstract
Abstract
Due to a coarse grain structure, crack lengths in precracked magnesium aluminate (MgAlO4) spinel specimens could not be measured optically, so the crack lengths and fracture toughness were estimated by strain gage measurements. An expression was developed via finite element analysis to correlate the measured strain with crack length in four-point flexure. The fracture toughness estimated by the strain gaged samples and another standardized method were in agreement.
