Abstract:Accurate analysis of composite delamination using interface elements relies on having sufficient elements within a softening region known as the cohesive zone ahead of a crack tip. The present study highlights the limitations of existing formulae used to predict numerical cohesive zone length and demonstrates modifications necessary for improved accuracy. Clarification is also provided regarding the minimum number of interface elements within the cohesive zone. Finally, appropriate values of numerical interfacial strength are examined. The results presented will aid the application of mesh design techniques that both preserve numerical accuracy, whilst minimising computational expense. Where applicable, subscripts I, II and m are used to denote properties under mode I, mode II and mixed mode loading respectively. Keywords

“…It is evident that for a mode II interfacial strength of 30MPa, as applied by previous authors [15,28], the analysis cannot accurately capture the peak load prior to crack propagation. This is due to a significant loss of stiffness during the elastic loading regime.…”

“…Robinson et al [180] proposed a damage parameter that was split into two parts: one for the static portion of delamination growth and one for the fatigue portion. The evolution of this damage parameter followed the relation proposed by Peerlings et al [181] and the interface elements and cohesive laws were based on the work of Alfano and Crisfield [182].…”

An overview is given of the development of methods for the prediction of fatigue driven delamination growth over the past 40 years. Four categories of methods are identified: stress/strain-based models, fracture mechanics based models, cohesive-zone models, and models using the extended finite element method. It is highlighted that most models are phenomenological, based on the observed macro-scale behaviour of test specimens. It is suggested that a more physics based approach, focusing on elucidating the mechanisms involved, is needed to come to a full understanding of the problem of delamination growth.

“…However, those studies were almost all carried out based on the fatigue tests under constant amplitude fatigue load. There are several common fatigue life evaluation methods of FRP, such as the experimental method based on S-N curve [1,2], residual strength degradation model [3,4], residual stiffness degradation model [5], energy dissipation model [6,7], fatigue modulus model [8], and numerical analysis [9][10][11][12]. These models or methods have distinct advantages and disadvantages.…”

A new research method based on vibration testing for the vibration fatigue of FRP was proposed in this paper. Through the testing on a closed-loop controlled vibration fatigue test system, the vibration fatigue phenomenon of typical carbon-fiber-reinforced plastic (CFRP) cantilevered laminate specimens was carefully studied. Moreover, a method based on the frequency response function was proposed to monitor the fatigue damage accumulation of specimens. On the basis of that, the influence factors that affect the vibration fatigue life of CFRP were experimentally studied. The influence of amplitude probability distribution of the vibration load spectrum on the fatigue life was deeply explored. Compared with Gaussian random vibration, the non-Gaussian random load has a significant impact on the vibration fatigue life of CFRP. The experimental results also showed that the magnitude of power spectral density (PSD) has a significant effect on the vibration fatigue life of specimens. For Gaussian vibration load, the frequency bandwidth almost has no effects on the vibration fatigue life of CFRP. However, for non-Gaussian vibration load, it has a great impact on the fatigue life. When PSD magnitude and frequency bandwidth are constant, the root mean square (RMS) is proportional to the vibration fatigue life of composites.
