Composite materials, particularly laminated fiber-reinforced polymers, have revolutionized aerospace, automotive, and civil engineering due to their high stiffness-to-weight and strength-to-weight ratios. However, analyzing the bending behavior of composite plates is more complex than isotropic plates due to orthotropic properties, layup sequences, and coupling effects (bending-stretching coupling).
