“…4. The fatigue life was increased with reduced reference stress in both GFRP composites, a similar trend observed by Philippidis and Vassilopoulos [35] in GFRP under MWISPERX load spectra. However, it may be clearly seen that, for a given reference stress, the GFRP-hybrid composite exhibits an enhanced fatigue life compared to the GFRP-neat composite.…”

“…The predicted fatigue life for GFRP-hybrid composite is conservative and lower by about two times when compared to experimental observations. It may be noted that a wide difference has been observed in the predicted and experimental fatigue lives of composites under various types of block and spectrum load sequences [35,49,50]. Considering such wide scatter in correlation between predictions and experiments, the present results provide a reasonably good correlation…”

“…Van Paepegem and Degrieck used the numerical simulation to study the effect of loading sequence and block loading on the fatigue of fiber-reinforced composites [17]. Philippidis and Vassilopoulos studied the fatigue properties of glass fiber-reinforced plastic (GFRP) by using the load spectrum WISPERX, which is often used in the study of wind turbine blades, as well as the actual load spectrum derived from the working environment of aircraft rotors [18]. Vassilopoulos et al studied the fatigue life simulation method of GFRP under irregular load and designed special numerical calculation software CCfatigue [14,19].…”

“…Fatigue data for the material systems used in the analysis presented was only available for R=10, R=0.1; Ultimate Tension Strain (UTS) and Ultimate Compression Strain (UCS). The Piecewise Linear methodology ( Figure 7) has shown good accuracy in predicting fatigue life with limited amount of test data, therefore it was used (Philippidis and Vassilopoulos, 2004). This method requires a limited amount of test data and performs linear interpolation between the known data points.…”
