| 摘 要： | 根据连续损伤理论，考虑到了损伤能释放率等引起损伤的重要因素，提出了一个各向异性疲劳损伤模型。此模型结构简单，适用于各种各向异性材料。利用该模型对玻璃聚酯复合材料层板在单向受力情况下进行了寿命预测，预测值与实验值符合较好

| Abstract: | A anisotropic fatigue damage evolution model, based on the theroy of continuum damage mechanics, is proposed in consideration of the important factors which induce material damage, for example, the damage strain energy release rate etc. The model simply constructed can be used for various anisotropic materials. The life and damage of the glass/polyester composite specimens are predicted. Theoretical predictions are in good agreement with experimental results. |
