"This module aims to develop a basic understanding in modern lightweight composite materials which are being used in an ever-increasing range of applications, especially in the growing UAV market. Basic knowledge of composites will allow engineers to understand the issues associated with using these materials, as well as gain insight into how their usage differs from other engineering materials. The finite element analysis (FEA) technique will be introduced as a tool to perform stress analysis of engineering problems, and commercial FEA software will be used. Fundamental concepts of the FEA and various formulations and element types will be covered.
