From the author: Uniaxial fatigue behavior of an epoxy resin was investigated with a recently established non-contact real-time strain measurement and control system. A relation of strain amplitude vs. fatigue life for fully-reversed strain-range-controlled uniaxial fatigue tests was obtained. Quantitative analyses of evolutions of various mechanical properties (including stress range, elastic modulus, nonlinear stress-strain relation, dissipated strain energy density, etc.) during entire fatigue life period were carried out based on recorded stress-strain data. From the evolution of the stress-strain hysteresis loops, a gradual degradation of modulus and a decrease of nonlinear effect in stress-strain response were observed. It was also found that these two phenomena were independent of the loading control mode (stress-control or strain-range-control) and the mean stress/strain values in the cyclic loading. Fractographic analysis was also performed and the mechanism of crack initiation and propagation of the epoxy material under cyclic loading was investigated. POLYM. ENG. SCI., 47:780-788, 2007.
