In this paper, stress distribution and deflection in sandwich plates with functionally graded nanocomposite face sheets have been carried out by a first order shear deformation theory (FSDT) based mesh-free method.
In the 2D model, the specification of the computational field is in terms of a distance of traverse z along an axial direction as well as a variable distribution of deflection (i.e. polar) angles θ where −π/2<θ<π/2, and corresponding symmetry is assumed for the range of azimuth angles (0<φ<2π).

In their experiment Stern and Gerlach found only two deflections, not the continuous distribution of deflections that would have been seen if the magnetic moment had been oriented in any direction.
Figures 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25 and 26 demonstrate the distribution of bending moment and deflection results along sections A, B, C, D, E, F and G in the considered slab (see Fig. 8).

(5) In terms of the deflection distribution, the donut-type voided slabs demonstrated equivalent deflection distribution in both the X- and Y-directions.

The distribution of the deflection angles to the different magnet types has been optimized.
Comparison with experimental data indicates the proposed variation method can accurately predict the plastic normal strain distribution and the deflection of steel box beams.
