This paper investigates the application of a novel foldable material in the sandwich plate subjected to multi-field loading. The analytical formulation is derived using the virtual work principle. The stretchable kinematic modeling is extended in order to arrive at more accurate results and modeling. The constitutive relations of the sandwich-reinforced core are derived using the overall and effective material properties of graphene origami-reinforced core using the Halpin-Tsai micromechanical model. The analytical solution is obtained in order to present the parametric results in terms of characteristics of the 3D nanofillers and multi-field loading parameters.

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.

A novel composite structure composed of graphene origami reinforcement integrated with piezoelectric/piezomagnetic layers is defined in this paper. The Material composition is assumed as steel novel metamaterials. The proposed model can be used as a diving board in swimming. The vibrational-based formulation is extended using an advanced higher-order thickness-stretchable model. The governing motion equations are derived using Hamilton’s principle through the computation of strain and kinetic energies as well as external work. The constitutive relations are extended for the composite core in terms of volume fraction, folding degree, and thermal load using some modifier functions using Halpin-Tsai micromechanical models for modulus of elasticity, Poisson’s ratio, thermal expansion coefficient, and density. The natural frequency responses are derived using the analytical method in terms of characteristics of graphene origami such as thermal load, foldability parameter, and amount of reinforcement. Furthermore, an investigation on the impact of initial electro-magneto-mechanical loads is studied on the responses.

In this article, we organize a stretchable-thickness model to present a frequency analysis for a composite plate applicable in badminton court which is reinforced with origami graphene. A higher order kinematic model is extended in this work including three bending, shear, and stretching functions, where the stretching functions is responsible for satisfying the out of plane shear strains and stresses at top/bottom surfaces of the badminton equipment. The sport or composites plate is manufactured from a copper matrix reinforced with graphene origami where the effective material properties are calculated based on micromechanical models as a function of volume fraction and folding degree of graphene origami, material properties of matrix and reinforcement and temperature. The numerical results are presented with changes of volume fraction, folding degree of reinforcement, and thermal loading along the thickness direction. The main novelty of this work is accounting thickness stretching deformation for the analysis of a graphene origami reinforced plate and investigating the responses of graphene origami as a new reinforcement. A verification investigation is presented for approve of the methodology, and solution procedure. An investigation on the order of deformation is presented for various thickness ratio of the badminton sport plate.
