Abstract
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.
