飞机结构疲劳 meaning in English

aircraft fatigue

General requirements of fatigue test for aircraft structure
飞机结构疲劳试验通用要求
The second part concerns about the fracture analysis of cracked metalic structures . the last part investigates the behavior of impact dents on aircraft windshield glass and their possibility to be analyzed using fracture mechanics . in chapter 1 , a review is made to the resent developments of cumulative damage models and fatigue life prediction methodology of composite laminates
本论文研究飞机结构疲劳和损伤容限分析中的若干问题，按研究的对象(材料、结构)可以大致划分为三个组成部分：复合材料层压结构疲劳分析，第一章第三章；金属结构断裂分析，第四、五章；座舱盖玻璃撞击损伤的断裂分析，第六章。
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。
