Laminate plate and shell stiffness classical lamination theory CLT

7 Laminate plate and shell stiffness classical lamination theory (CLT) 

Many composite stractures can be described and analysed as thin laminated shells or plates composed of several laminae stacked sequentially, each aligned at a specific angle with respect to a material reference axis, by convention the jc-axis. Classical lamination theory is quite suitable for analysing thin laminated plates or any thin laminated shell that can be reduced to an equivalent plate. 

32 Off-axis in-plane shear modulus for carbon/epoxy. 

Special notations are used for symmetric laminates, laminates with adjacent laminae of the same orientation or of opposite angles, and so on. 

34 Off-axis Poisson s ratio for carbon/polyimide (after [14]).
