摘要: Fatigue crack growth tests were conducted on double cantilever beam bonded specimens with the aim to characterize an adhesive for structural applications. The in lab air at two different load ratios, R=Pmin/Pmax, and loading frequencies, f. Crack propagation was monitored using unloading compliance method. da/dN vs. ΔG experimental showed typical sigmoidal shape of bulk materials. closure considerations successfully used explain R-ratio effect. role frequency also addressed.
