内容記述 | Crack propagation rate in 7075-T6 tension plates was determined for central cracks initially oriented in 45, 60, and 90 deg. to the width direction of the tension plates which were loaded cyclically. Opening and sliding mode of stress intensity factors, KI and KΠ were determined by the finite element method for curved cracks generated from these initially slanted saw-cut notches. Crack propagation rates, Δa/ΔN, were then plotted against the maximum opening mode of stress intensity factor, KI, in the presence of sliding mode of stress intensity factor, KΠ. Comparison between the corresponding crack propagation rates in control specimens without KΠ showed that the rate is definitely increased in the presence of KΠ. | |||||
