Sub-critical crack growth in a ceramic and a ceramic composite: Effects of monotonic loads, cyclic loads, and high temperatures

Advanced ceramics have toughened microstructures which resist crack propagation, and also allow considerable sub-critical crack growth prior to failure. The sources of toughening processes are the microstructural elements in the crack wake which induce closure tractions on the crack. This experimental and theoretical study examines the sub-critical crack growth behavior in alumina and SiC$\sb{\rm f}$/SiC composite under conditions which degrade the toughening processes.
