    thermal expansion coeffcient

    i have an important qustion i want to know how to transform the thermal expansion coeffcient tensor (alpha) 6x6 when the fiber orientation changed from 0 to 30 degree for example? are there any equations for that ? how i can reduce this tensor from 6x6 to 3x3 ?

    orthotropic lamina properties

    Dear i have lamina with orthotropic properties how i can derive an expression for Gxy (equivalent shear stress) in terms of E1, E2,v12,G12, and theta ???? where: E1: is the elastic modulus at the fiber direction E2: elastic modulus at transverse direction v12: is the main possion ratio...
