For validation, replace the laminate with a single isotropic layer (set E1=E2, G12=E/(2(1+nu)), same thickness). Compare to analytical formula:

[ D_11 \frac\partial^4 w\partial x^4 + 2(D_12 + 2D_66) \frac\partial^4 w\partial x^2 \partial y^2 + D_22 \frac\partial^4 w\partial y^4 = q(x,y) ] Composite Plate Bending Analysis With Matlab Code
