Composite Plate Bending Analysis With Matlab Code [new] Jun 2026

% Shear correction factor (5/6 for rectangular section) K_s = 5/6; As = K_s * As;

Here [B] relates curvatures to nodal DOF, and [D] is the laminate bending stiffness matrix. Composite Plate Bending Analysis With Matlab Code

We use a (size 2a×2b in local coordinates). Each node has 3 DOF: w, θx = ∂w/∂y, θy = -∂w/∂x. % Shear correction factor (5/6 for rectangular section)

For a simply supported cross-ply laminate, this simplifies to ( w = 0 ) and ( \partial^2 w / \partial n^2 = 0 ) on edges. As = K_s * As
