This paper discusses static and dynamic response of nanoplate resting on an orthotropic visco-Pasternak foundation based on Eringen’s nonlocal theory. Graphene sheet modeled as nanoplate which is assumed to be orthotropic and viscoelastic. By considering the Mindlin plate theory and viscoelastic Kelvin-Voigt model, equations of motion are derived using Hamilton’s principle which are then solved...

Nonlocal vibration of double-smart nanobeam-systems (DSNBSs) under a moving nanoparticle is investigated in the present study based on Timoshenko beam model. The  two  smart  nanobeams (SNB) are  coupled  by  an  enclosing  elastic  medium  which  is  simulated  by  Pasternak foundation. The energy method and Hamilton’s principle are used to establish the equations of motion. The detailed param...

In the present paper, a novel unconstrained higher-order theory (UCHOT) is applied to analyse free vibration of cylindrical sandwich shells with nanocomposite face sheets reinforced graphene platelets. UCHOT considers shear and thickness deformations. It assumed that cylinder includes soft core which embedded between functionally graded platelets composites (FG-GPLRC). FG-GPLRC sheet consists s...

Due to the unique hydrothermal environments, frost heave failure of concrete lining water conveyance canals in cold regions is still frequent. The deformation after heaving and stress distribution calculated by mechanical model can be reference for design. However, previous research mainly focused on cross-section while having little attention longitudinal nonuniform damage. In this study, a bo...

The aim of this paper is to investigate the buckling behavior porous Functionally Graded Materiel (FGM) cylindrical shells based on Donnell shell theory. In context, we develop an explicit analytical expression which takes into consideration effect porosities through thickness structure and that elastic foundation using a modified power-law function models Winkler Pasternak, respectively. We us...

Static analysis of shear deformable plates resting on two-parameter foundations is presented by the method of discrete singular convolution (DSC). The influence of foundation parameters on the deflections of the plate has been investigated. Numerical studies are performed and the DSC results are compared well with other analytical solutions and some numerical results.

“There’s no such thing as a free lunch” is an adage described over one century ago, which became popular by Professor Milton Friedman, in 1975. It came to my mind when reading the interesting editorial by Pasternak and Glina.(1,2) Working on both sides, as an author of journals and a reviewer, I am aware of the importance of a good review. It is powerful to enhance the description of results in...
