Overview

Theoretical model shows temperature-dependent fatigue performance in fiber-reinforced polymer composites, indicating significant damage evolution.

Key Points

  • To establish a theoretical model for temperature and damage dependent fatigue strength of fiber-reinforced polymer composites.
  • Developed a temperature and damage dependent fatigue strength model (TDDFS) using the Force-Heat Equivalent Energy Density principle.
  • Analyzed the influence of temperature, load level, and layup configurations on fatigue strength.
  • Conducted comparisons between model predictions and experimental data.
  • The TDDFS model reliably predicts fatigue strength across different temperature ranges.
  • Demonstrated the evolution of damage in fiber-reinforced polymer composites with increasing temperature.
  • Experimental data confirmed the model's predictions and highlighted critical insights into fatigue performance.
