Composite plate bending analysis involves determining the deflections, strains, and stresses in a multi-layered structure subjected to transverse loads. Because composite laminates are anisotropic and inhomogeneous through their thickness, their behavior is significantly more complex than that of isotropic plates. Key Theoretical Frameworks
Based on the Reissner-Mindlin model, this theory accounts for transverse shear by assuming that normals remain straight but not necessarily perpendicular to the mid-surface. It is more accurate for "moderately thick" plates but requires a shear correction factor to adjust for the assumption of constant shear through the thickness. Composite Plate Bending Analysis With Matlab Code
) matrices are computed by integrating through the thickness. It is more accurate for "moderately thick" plates

Composite plates are widely used in various engineering applications, such as aerospace, automotive, and civil engineering, due to their high strength-to-weight ratio and stiffness. However, analyzing the bending behavior of composite plates can be complex due to their anisotropic material properties. This guide provides an overview of composite plate bending analysis using MATLAB code.
The code is structured into main script and functions. It performs:
