【摘要】 本文首先阐述了飞机结构中的力学问题。基于我们近几年的研究工作,从若干方面介绍了力学在飞机结构设计中的应用与发展,如机身的广布疲劳损伤蔓延的断裂力学计算和风险评估,鸟撞驾驶舱盖和起落架落震的强度问题,以及低速冲击作用下机翼的复合材料层合板的脱层和基体断裂问题等。更多还原

【Abstract】 Mechanical problem related to the aircraft structures design is described in this paper.Based on the research and development works in recent a few years,some applications and developments for the mechanics used in the aircraft structures design are introduced,for example,fracture mechanics computation and risk evaluation for the widespread fatigue damage (WFD) in the fuselage,the strength problems for the windshield against the bird-impact and dynamic problems of the landing gear,as well as the delamination and matrix cracking in the composite laminates under the low-velocity impact.更多还原
