Abstract
Fatigue tests with frequency of 0, 1, 5, 10, and 20 Hz were carried out on three types of cracked alumina ceramics. A specimen surface was replicated at the maximum stress during one cycle. The crack length was measured on plastic-replica with optical microscope and the crack opening displacement was observed on metal-replica with scanning electron microscope. The fatigue crack propagation rate, da/dN, was not controlled by the stress intensity factor. However an equivalent crack propagation rate da/dt|eq was controlled by the effective stress intensity factor at crack tip obtained from COD, independent of the frequency with some percent scatter.
