# Normal and Shear Coupling for Unidirectional Angle Ply

Normal and Shear Coupling for Unidirectional Angle Ply

This Demonstration shows the coupling between normal stress and shear strain for a unidirectional, fiber-reinforced angle ply. By varying the applied stress, the material properties of the composite, and the ply angle , you can observe the degree of coupling between normal stress and shear strain for an angle ply. Note that for plies of 0 and 90 degrees, there is no coupling because they behave as orthotropic materials. The effect of varying the longitudinal and transverse stiffness, along with Poisson's ratio, can also be observed.
