Abstract

Reducing weight and improving strength of structures have always been major design goals in the aerospace industry since its inception. In particular, strength directly affects the safety and serviceability of an airplane and is therefore of great importance in structural design. Improving the strength of an airframe can effectively increase its damage tolerance in different failure modes, such as fracture, fatigue and impact damage. To pursue these goals, optimization techniques, which aim to seek for the “best solution” in mathematical models, can be applied in the structural design process. In addition, usage of lightweight carbon fiber reinforced composite laminates further serves this purpose....
