Application of fracture mechanics to heterogeneous systems — prediction of fatigue life of ceramics

  • N. Kamiya

A prediction of fatigue life and fracture stress of ceramics of a heterogeneous system was made by application of fracture mechanics based on slow crack growth. It was shown that the prediction of fatigue life and fracture stress in ceramics of heterogeneous system in general could be dealt with in a similar way to those of ceramics of a homogeneous system. Experimental examination of the validity of the prediction was made with LAS glass ceramics (Li2O-Al2O3-SiO2) at various stages of devitrification as well as foamed glass. These results proved the validity of the formulae derived.
