Small Deflection Problem of Polar Material Spiral Laminates

This paper discusses the effect of spiral laminae of polar materials on the stiffness of laminates and gives out the relation between spiral angle and equivalent elastic constants of the spiral laminates including asymmetric stresses and coupled stresses.It is concluded that the appropriate choice of the spiral angle of laminae can greatly enhance the stiffness of laminates.
