Abstract

This paper deals with crack propagation from circular holes in SS 304 plates under fatigue and fatigue with hold-time at 600°C. In pure fatigue loading, short crack propagation in terms of ΔK is strongly affected by crack closure; this effect is non-existent when the J-integral, ΔJ(f), is used. Neither fatigue nor creep parameters (ΔJ(f), ΔJ(c) and J(*)) alone gave adequate representation of crack growth for the three frequencies, 1, 1.6 x 10^-2 and 3.3 x 10^-3 Hz. However, the sum of ΔJ(f) and ΔJ(c) resulted in a good correlation of crack growth for all frequencies. Fractographic analyses are used to explain the different conclusions concerning the choice of fracture mechanics parameters.
