    Purpose: Thermal stress and strain analyses of a thickness-stretched shear deformable microplate is studied in this paper based on principle of virtual work through a micro scale dependent theory. Methods: The general constitutive relations are developed in three dimensional based on generalized Hooke’s law. Thermal strain is included in the governing equations based on various temperature rising along the thickness direction. Results: An extended parametric analysis is performed in this paper after solution of the governing equations based on Navier’s technique. Numerical results are plotted in terms of temperature rising, micro-scale parameter along the thickness direction. Conclusions: The important difference of this paper with available materials in the literature is concurrent effect of thickness stretching ability and micro scale parameter.

    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.
