% Assemble global stiffness matrix K = [D11, D12, D16; D12, D22, D26; D16, D26, D66];

% Display results fprintf('Deflection: %.2f mm\n', w * 1000); fprintf('Rotation (x): %.2f degrees\n', theta_x * 180 / pi); fprintf('Rotation (y): %.2f degrees\n', theta_y * 180 / pi); This code defines the plate properties, material stiffness matrix, and flexural stiffness matrix. It then assembles the global stiffness matrix and solves for the deflection and rotation of the plate under a transverse load.

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

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.
