Fatigue crack growth in ceramic materials at ambient and elevated temperatures
Abstract
The mechanics and mechanisms of stable fatigue crack growth in a wide variety of ceramics and ceramic composites are examined in detail. Experimental results on crack growth, numerical analyses and microscopic observations of crack-tip damage zones are presented to illustrate fatigue processes with: (1) a mode of failure that is distinctly different from that seen under static loads; (2) kinematic irreversibility of microscopic deformation which leads to cyclic damage zones, analogous to cyclic plastic zones in metal fatigue; and (3) crack velocities which are distinctly different from those found under static load failure due to a mechanical-environmental synergistic effect or as a result of purely mechanical contact phenomena such as crack closure, crack bridging by grains or reinforcements, or wedging of crack faces by debris particles. 19 refs., 6 figs.
