Abstract

Fatigue crack propagation rate in carbon steel at resonance is investigated. The model under consideration is a diametrically loaded circular steel ring. The compliance method was simulated using the finite element analysis to determine the stress intensity factors for the ring with two diametrical cracks emanating from the inside surface, for two different boundary conditions. A procedure to predict the fatigue crack propagation rate in resonant structures is presented. Tests were carried out on circular rings made of medium carbon steel SAE 1045, to investigate the sensitivity of the stress intensity factor to the crack length for short cracks. Paris' law was considered valid in this investigation. However, it is recommended to verify experimentally the applicability of Paris' law to describe fatigue crack propagation rate at resonance in further investigations.Dept. of Civil and Environmental Engineering.
