Nonlinear numerical thermoelastic frequency prediction of hybrid smart (SMA bonded) nanocomposite doubly curved structure

This research predicted the thermoelastic modal responses of smart nanocomposite structure utilizing two different types of nonlinearities (geometry and material). The structural model is derived mathematically using full form of geometrical nonlinearity (Green-Lagrange) and higher-order kinematics (through thickness and displacement variation is constant). Additionally, an equivalent single-layer theory has been adopted for the formulation and material nonlinearity introduced for shape memory alloy with temperature variation. The desired governing equation is solved numerically using nonlinear finite element steps. Numerical solution accuracy is verified by conducting the mesh refinement test and comparing the results with published domain. A set of numerical analysis are conducted by changing the parameters (material, geometry and environment). The current solution/model efficiencies are discussed in detail.
