Bending Analysis of Laminated Composite Plates Bending analysis of composite plates is essential for designing high-performance structures in aerospace and automotive engineering. Because composite plates consist of multiple orthotropic layers, their response to transverse loads depends on the stacking sequence and fiber orientation.

The moment-curvature relation:
ABD Matrix: The core of composite analysis, where A represents extensional stiffness, B represents coupling stiffness (essential for unsymmetric layups), and D represents bending stiffness. Theories used: CLPT: Best for thin plates ( ) where shear deformation is negligible. Post-processing % Extract w at nodes W =
u(x,y,z) = u0(x,y) - z * ∂w/∂x
v(x,y,z) = v0(x,y) - z * ∂w/∂y
