Modeling of fatigue behavior based on interaction between time- and cyclic-dependent mechanical properties

A general constitutive equation was established using the theory of viscoelasticity in order to consider the interaction of the time- and cyclic-dependent mechanical properties of laminated composites. This equation was solved for two specific loading patterns, (1) stress unloading to zero stress level (recovery solution), and (2) load control sinusoidal loading (fatigue solution), and was subsequently imported to model tensile-tensile...
