    This analytical paper investigates the impact of initial electric potential as well as graphene origami characteristics on the deformable/foldable behavior of the sandwich double curved shell composed of a graphene origami-reinforced copper core sandwich by intelligent layers at top/bottom as sensor, actuator and energy harvester. The stretched and foldable model is extended for the description of the kinematic and constitutive relations, respectively. The variational-based formulation is extended for the derivation of the governing equations. The solution procedure is extended for the special boundary conditions to seek the impact of multi-field loading and material constituent characteristics on the electro-thermo-folding responses of the sandwich hybrid shell. As a quantitative result, one can arrive at 10% decrease in deflection with 2% addition of graphene origami reinforcement.

    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.
