Composite Plate Bending Analysis With Matlab Code May 2026

% 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.

% Assemble global stiffness matrix K = [D11, D12, D16; D12, D22, D26; D16, D26, D66]; Composite Plate Bending Analysis With Matlab Code

% Define flexural stiffness matrix D11 = (1/3) * (Q11 * h^3); D22 = (1/3) * (Q22 * h^3); D12 = (1/3) * (Q12 * h^3); D66 = (1/3) * (Q66 * h^3); D16 = (1/3) * (Q16 * h^3); D26 = (1/3) * (Q26 * h^3); % Display results fprintf('Deflection: %

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.
