Composite Plate Bending Analysis With MATLAB Code

Abstract

Provide a concise summary (150–200 words) describing objectives: develop bending theory for laminated composite plates, derive governing equations using Classical Laminate Theory (CLT) and First-Order Shear Deformation Theory (FSDT), implement numerical solution in MATLAB, validate against analytical solutions and FEM, and demonstrate parametric studies (layup, aspect ratio, boundary conditions, transverse shear effects).
