THREE DIMENSIONAL STRESS STATE OF SMART COMPOSITE LAMINATED CROSS PLY USING HSDT WITH ZIG ZAG FUNCTION

Thermal analysis of smart composite laminated plate using higher order theory with zig zag function. To develop the analytical procedure and to investigate the thermal characteristics fo r a three dimensional cross ply laminated plate. The material is considered to be orthotropic under thermal load based on higher order displacement model with zig - zag function, without enforcing zero transverse shear stress on the top and bottom faces of t he laminated plates. The related functions and derivations for equation of motion are obtained using the dynamic version of the principle of virtual work or Hamilton’s principle. The solutions are obtained by using Navier’s and numerical methods for anti - s ymmetric cross - ply with specific type of simply supported boundary conditions SS. Computer programs have been developed to find the stresses and deflections for various aspect ratios, side thi ckness ratios (a/h) and voltage
