Thermo-foldable bending analysis of tunable shells using a higher-order modeling

Abstract

This article investigates effect of a higher order kinematic modeling on the elasto-static bending results of a shell in double curved form. The graphene origami is introduced in this article as a novel nanofiller with some chemical process to arrive at a controllable material. A copper matrix is used as main constituent reinforced with folded graphene origami. The virtual work principle is used to derive governing equations of the thickness-stretchable shell. After derivation of the governing equations and to arrive at the solution, a class of formulas is used from valid sources for effective material properties of the shell. A verification test is presented before exploring the effect of all main affecting parameters of the graphene origami and ambient on the bending results. The results of this work may be used in the analysis of structures with controllable responses.
