Composite Plate Bending Analysis With Matlab Code

To analyze a laminate, we follow a four-step reduction process:

Running the code with the provided cross-ply layup [0/90/0/90] under 1000 Pa uniform pressure gives a maximum deflection of approximately 0.5–0.8 mm depending on exact dimensions and mesh. The deformed shape plot confirms symmetric bending. Composite Plate Bending Analysis With Matlab Code

Key observations:

CLPT assumes that straight lines normal to the mid-surface remain straight and normal after deformation (no shear deformation). Displacement field: To analyze a laminate, we follow a four-step

u(x,y,z) = u0(x,y) - z * ∂w/∂x
v(x,y,z) = v0(x,y) - z * ∂w/∂y
w(x,y,z) = w0(x,y)
