Fracture Mechanics of Ceramicse failure behaviour. The main problem in the application of the simple fracture mechanics relation is the existence of a rising crack growth resistance curve, which is caused by crack bridging forces behind the advancing crack tip or by transformations in front of the crack tip. The increasing crack

健谈

Weakest—Link Failure Prediction for Ceramicsnt bend and biaxial test results is discussed in the light of current theoretical understanding. There remain a number of unresolved aspects and a new, ‘damage mechanics’ approach is mooted for further consideration.

Judicious

Creep of Non—Oxide Ceramics Considering Oxidative Influencesequations presented, and the parallel microstructural mechanisms discussed. For porous silicon nitride the pore size rather than amount is critical in determining creep under oxidation. In dense sintered silicon nitride the presence or absence of viscous glassy phases is the main factor controlling
