“…In order to simulate the fatigue damage behavior and to predict fatigue life of fiber-reinforced composites, in recent years several methodologies that implement progressive failure analysis and appropriate constitutive models with damage accumulation laws have been developed. In open literature, fatigue progressive damage models have been extensively established from macro to microscopic scales by means of theoretical analysis methods, finite element solutions and experiments [10][11][12][13][14][15][16][17]. Montesano et al [18] have established a damage mechanics based model that takes into account local multiaxial stresses as well as variable amplitude cyclic loading.…”

This work presents a fatigue damage meso-model for fiber-reinforced plastic composites, in which the effect of stress ratios on the off-axis fatigue behavior is taken into account. The non-dimensional effective stress concept is introduced in the continuum damage mechanics method. Damage growths and fatigue failure are studied along axial, transverse and shear directions at meso-scale level. The proposed model is validated through numerical simulations that describe the meso fatigue damage accumulation and the fatigue life for off-axis unidirectional fiber-reinforced plastic composite laminates of arbitrary fiber orientation under different stress ratios. It is shown that the fatigue damage behavior and fatigue life for off-axis unidirectional glass/epoxy and carbon/ epoxy composite laminates are adequately described by the proposed fatigue model over the range of different stress ratios.

“…Equations (26) to (30) may be used to check the fatigue fibre breakage, matrix cracking and/or interfacial debonding, and interlaminar shear failures, respectively. The material constants (α, β, δ, φ, and γ) appeared in these equations may be determined through calibrations based on the unidirectional fatigue tests, at arbitrary R ratios.…”

Two frameworks are employed to develop two distinct categories of multiaxial high cycle fatigue life assessment models for composite components experiencing general and random loading conditions. In this regard, the decay in the material properties with cycles is also taken into account. It is obvious that in multilayer components, the fatigue failure is a progressive process that may be accompanied by gradual or sudden changes in the material properties and, consequently, the resulting stresses. In addition to using the traditional progressive damage analyses, a new concept is proposed for tracing of the localized fatigue failures more accurately. It is postulated that generally, the stress components have distinct frequencies, phase shifts, and mean values that all vary with time in a random manner. The proposed fatigue criteria, especially, the equivalent-stress-based ones, are capable of predicting various fatigue failure modes, such as the fibre breakage, matrix cracking, and interfacial debonding. A special and comprehensive fatigue failure tracking and cycle counting algorithms that are capable of handling the mentioned general peculiarities are proposed. The proposed HCF criteria and the relevant fatigue life assessment algorithm are then implemented on a composite multilayer monoleaf spring of a realistic vehicle under a random field-measured loading condition, as a typical component, and the results are compared and the experimental results conducted by the authors, for accuracy investigations. The considered stochastic road inputs have been chosen on the basis of the consumption times and field measurements.
