This lesson covers the comprehensive understanding of the theory of composite shells. The lesson explains the development and applications of composite and sandwich materials in various fields like aerospace, automobile, marine, and home decor products. It also discusses the difference between plate theory and shell theory, the lack of online resources for shell theories, and the importance of shell analysis in commercial software. The lesson further elaborates on the development of shell equations, the basic elements of structural engineering, and the different types of shells. It also provides an overview of the course structure, the key reference books, and the practical applications of the shell.

- The composite and sandwich materials, developed in the 1970s, have found applications in various fields like aerospace, automobile, marine, and home decor.
- Shell equations can be developed, which is slightly different from the plate and the basic elements of structural engineering.
- Shell finds huge usage in structural applications, which can be applied by understanding the bending, free vibration, buckling, post-buckling analysis of shells made of composites and sandwiches.
