摘要
将不可逆热力学和损伤力学应用于橡胶复合材料的疲劳研究,在大量试验工作的基础上,选择适当的热力学势函数,建立了橡胶复合材料的损伤演变方程和橡胶复合材料的疲劳寿命预报方程。应用本模型对单向橡胶复合材料的疲劳寿命进行了预报,发现理论预测值与试验结果比较符合。
Irreversible thermodynamics and damage mechanics are applied to fatigue damage of rubber composites Based on a large number of experiments, a suitable thermodynamics potential function is selected and then a nonlinear damage evolution equation of rubber composites and the fatigue life prediction equation of rubber composites is established The experiment results indicate a reasonable good agreement between the model and the actual data This shows that it is feasible for the established model to predict fatigue life of rubber composites
