Abstract
A Fatigue damage accumulation model based on the Paris law has been proposed for strain rate-sensitive polymer composite materials. A pre-exponent factor c2/f and strain-rate sensitive exponent n is introduced. Numerical analysis of the model has been performed using experimental data obtained in the literature. Both factors are found to enhance fatigue damage accumulation. The analysis also reveals that the extent of damage increases with decresing frequency and that the damage rate is more sensitive to the applied maximum stress than to the stiffness of the material.Citation
