Abstract: Over the years many shell finite elements has been developed for applications in aerospace, automotive and shipbuilding industries. Misuse or abuse of some of these shell finite elements in the relatively mature shell finite element technology is not uncommon. Some of these shell finite elements were based on the principles of classical shell theory in which the simplest one is the theory of Love. Others were based on intuitive or heuristic arguments. For reasons of economy, mathematical simplicity and accuracy, lower order flat triangular shell finite elements are popular among designers. This article is concerned with the review, development and application of triangular shell finite elements. Emphasis is on mixed formulation based lower order flat triangular shell finite elements. Finite element representation of shell structures is introduced. Linear analysis of static and dynamic, and nonlinear analysis of static and dynamic problems, are included in this article.
