Mode II crack propagation tests were conducted at high frequencies on carbon fiber/epoxy laminates under vibration fatigue at resonance. In parallel, classical fatigue tests were carried out at 10Hz on a servo-hydraulic machine in order to compare results in terms of Fatigue Crack Growth Rate (FCGR) vs Energy Release Rate (ERR) curves. Different load ratios were considered for classical tests. Frequency and load ratio effects were determined from both high and low frequency tests results. Using ...

Load ratio effect on fatigue crack propagation is explored on a carbon/epoxy composite material. The fatigue load could be better represented by their amplitude instead of their maximum value. Cumulative damage is then investigated by achieving consecutive fatigue tests on the same specimen. Consequences on the crack growth rate are highlighted. It is shown that the fatigue pre-crack length, as well as the building method of the fatigue pre-crack plays an important role in the fatigue crack prop...
