ABSTRACT

Composite materials are being widely used in modern structures, such as aircraft and space vehicles, because of high performance, high temperature resistance, tailoring facility, and light weight. Considerable research on the design and failure analysis of composite structures is being conducted. The results of experiments and research into composite materials show large statistical variations in their mechanical properties. Therefore, probabilistic analysis has to play an important role in structural assessment. This chapter presents reliability analysis methods for composite structures, considering several types of failure criteria: ultimate strength, fatigue, delamination, and creep.
