Application of 2D coupled algorithms to thermally induced dynamics of temperature-dependent nanocomposite cylindrical panels under transient heat shock.

The current investigation examines the thermal wave motion in a functionally graded cylindrical panel with carbon nanotubes exposed to rapid surface heating. The equivalent temperature-dependent material properties of the nanocomposite media are achieved by employing a modified homogenization technique. Due to the time-dependent nature of the applied heat function, the heat conduction equation is calculated transiently. Furthermore, due to the temperature dependency of the properties, the heat conduction equation is nonlinear and is solved by the combined finite-difference and Picard methods. The Crank–Nicolson time solving scheme is utilized to determine the temperature profile of each composite system point across time. The first-order shear deformation and Donnell strain theories regulate the system's motion equations. The combined 2D generalized differential quadrature and Newmark procedures are implemented to numerically simulate the composite structure's physical variables. Following verification, the effects of composite media parameters and panel characteristics on the shell reaction subjected to thermal shock are examined. [ABSTRACT FROM AUTHOR]
