    Foldability capacity is now introduced as a novel nanofiller reinforcement production procedure using some operation to control the mechanical, thermal and electrical properties in the sport equipment. Application of this type of nanofillers in the curved structures like pole vault shell leads to a novel engineering and sport shell shape structures. This article is organized to suggest a vibration-based formulation for analysis of folded reinforced curved shell sport structure subjected to thermal and mechanical loading. Using computation of kinetic, strain and external energies, one can arrive the motion’s equations using the minimization of total energy and Hamilton’s principle. Using solution of the motion’s equations through an analytical approach, the parametric analysis is presented. The verified test is presented for confirmation of the solution and trend of results.

    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.
