Consider a 2-ply lamination with all plies at 45 degrees and both layers have the same hardness Q as below 

Let's assume you have the matrix:

[Q] = [130 2.5

2.5 10 0 ]

    0 0 3.5                                                                                                                                         

(a). Calculate matrices A, B and D for 2-layer lamination

(b).The applied load is Nx = 100 kN/m. Lamina stress change in each layer in the lamination

calculate.

(c).Draw the outline of the deformed laminate.
