Abstract

The number of load cycles, N, load-point displacement (LPD) and crack- mouth-opening displacement (CMOD) compliance were measured in a series of fatigue tests on single-edge-notched concrete beams (SENB) under 4-point bending to investigate the kinetics of crack propagation in plain concrete. The prenotched beams were subjected to either a constant or variable pulsating load up to a maximum load level of about 75% of the static ultimate strength. Typically, the crack growth rate, dℓ/dN decreased for the first 8 mm of crack extension. The crack growth rate and the strain energy release rate, GI, are plotted versus the crack length to beam depth ratio, which is determined from the CMOD compliance measurements. The crack speed varied considerably along the crack path but increasing strain energy release rates produced on the average an increase in the crack speed. Finally, kinetic data from three beams subjected to a constant amplitude repeated loading is compared to the Paris model.
