For engineers and researchers, Matlab provides the ideal environment to bridge the gap between theoretical laminate theory and practical numerical solutions. This article provides a deep dive into the bending analysis of composite plates using the Classical Lamination Plate Theory (CLPT) and the Finite Element Method (FEM), complete with a robust, educational Matlab code implementation.
