I have found that in Antisymmetric Angle Ply Laminates, the shear deformation effect using any existing shear deformation theory works out to be zero.
Well, the classic theory of ideal composite does not take the shear effects into account. The extension seems to be straightforward.
Try the following steps:
1) use ideal model of composite (with unextensible fibers). Apply the normal strain. The unextensible fibres play the role of constraints
2) express the shear strain in material in terms of normal strains
3) substitute the expression of shear strain in the functional for elastic energy
4) stationary conditions of the functional for elastic energy deliver the required constitutive equations.
Dear Sir,
It is quite easy to calculate it if you have a look to the Classical Lamination Theory.
Furthermore, before go to analyze your laminate, consider your boundary conditions and load. To be more precise, let us know you aimed to determine deformation in which direction or plain?
Vladimir and Amin. Thanks for feedback.
I forgot to mention that I am working on higher order theories. This is not that difficult problem using Classical Lamination Theory CLPT. It was regarding higher order theories, with displacement approach.
