The ultimate strength of cf / ep quasi - isotropic laminates with different stacking sequences is experimentally and numerically investigated to study the influence of stacking structure or loading direction on the strength
摘要以碳纤维环氧树脂层合板为对象，研究了其最终强度与层合结构的关系，对于准各向同性层合板，其弹性性能不随方向变化。
The cumulative damage modes and their distribution regions on 7t / 4 quasi - isotropic laminates were reasonably simulated and the predicted fatigue lives agree well with the test results . residual strength evaluation is playing a significant role in damage tolerance analysis of structures . chapter 4 describes a simple procedure for the evaluation of residual strength of metallic structures with cracks developed b
提出按剩余西北工业大学博士学位论文:飞机结构疲劳和断裂分析中若干问题的研究强度等效和按疲劳寿命等效两种途径将撞击损伤当量化为表面裂纹，并根据有限的试验结果进行了尝试，得到了一些初步结果。
