Abstract
Graphene origami in a copper matrix is used as a composition of core in a sandwich panel between two piezoelectric/piezomagnetic layers. More accurate modeling of the composite sandwich structure is performed using a higher-order model including thickness stretching term. Principle of virtual work is used in order to derive governing equations in terms of resultant components of force and moment as well as electromagnetic loads.
The resultant components are derived in higher-order framework with accounting electric and magnetic potentials using the effective material properties of graphene origami in Halpin-Tsai and rule of mixture framework. The deformation/strain/stress components are analytically obtained in terms of thermal, mechanical, electrical, and magnetic loads as well as folding degree and content of graphene origami. Verification is performed for justification of the numerical results.
A foldability dependent parametric analysis is presented to show controllability of stress, strain and deformations along the thickness direction.
