Prediction of Fracture Toughness in Fibrous Si3 N4 Monolithic Ceramics

Abstract:

Article Preview

A fracture toughness model of fibrous monolithic ceramics revealed that the major factor that contributed to the fracture toughness in ceramics was the actual energy absorbed by crack propagation rather than the total work of fracture. The load-displacement curve and the crack propagation path were predicted using the derived model mirror image with that of experimental data.
