TL;DR: An analytical approach for static bending and buckling analyses of curved nanobeams using the differential constitutive law, consequent to Eringen's strain-driven integral model coupled with a higher-order shear deformation accounting for through thickness stretching is presented in this paper.

TL;DR: In this article, a nonlinear axisymmetric dynamic behavior of sandwich spherical and conical shells made up of CNT reinforced facesheets is studied, where the shell is subjected to thermal loads and discretized with three-noded axisymetric curved shell element based on field consistency approach.
Abstract: Owing to their superior mechanical and thermal properties, carbon nanotube (CNT) reinforced composite materials have wide range of applications in various technical areas such as aerospace, automobile, chemical, structural and energy. In this paper, the nonlinear axisymmetric dynamic behavior of sandwich spherical and conical shells made up of CNT reinforced facesheets is studied. The shell is subjected to thermal loads and discretized with three-noded axisymmetric curved shell element based on field consistency approach. The in-plane and the rotary inertia effects are included within the transverse shear deformation theory in the element formulation. The present model is validated with the available analytical solutions from the literature. A detailed parametric study is carried out to showcase the effects of the shell geometry, the volume fraction of the CNT, the core-to-face sheet thickness and the environment temperature on the dynamic buckling thermal load of spherical caps.
