摘要: A statistical model is developed for the prediction of fatigue life unidirectional composite laminae subjected to multiaxial loading. This based on experimental data behavior those uniaxial The method extension generalized residual material property degradation previously describe materials under a wide range stress ratios, combined with nature static and failure fiber-reinforced composites. distribution function determined in terms strength different loading modes, which considered be stochastic nature. any are evaluated statistically by using longitudinal, transverse in-plane shear directions, experimentally through characterization. application evaluation biaxial shows good agreement corresponding data.
