MATLAB Code for Composite Plate Bending

For a simply supported symmetric plate, you can use the Navier solution. The maximum deflection at the center can be approximated using the effective bending properties derived from the $[D]$ matrix. Composite Plate Bending Analysis With Matlab Code

What do you need? (e.g., fully clamped edges) What do you need

% Strain at bottom and top: e = e_0 + z*k % Assuming e_0 = 0 for pure bending symmetric case, otherwise use epsilon_0 strain_bot = epsilon_0 + z_bot_k * kappa; strain_top = epsilon_0 + z_top_k * kappa; What do you need? (e.g.
