where $M_x$, $M_y$, and $M_{xy}$ are the bending and twisting moments, $q$ is the transverse load, $D_{ij}$ are the flexural stiffnesses, and $\kappa_x$, $\kappa_y$, and $\kappa_{xy}$ are the curvatures. % Solve for deflection and rotation w =

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. This guide provides an overview of composite plate

The following MATLAB code performs a bending analysis of a composite plate using FSDT:

% Define material stiffness matrix Q11 = E1 / (1 - nu12^2); Q22 = E2 / (1 - nu12^2); Q12 = nu12 * Q11; Q66 = G12; Q16 = 0; Q26 = 0;
