Semi-analytical static analysis of nonlocal strain gradient laminated composite nanoplates in hygrothermal environment

Abstract In this work, the bending behavior of nanoplates subjected to both sinusoidal and uniform loads in hygrothermal environment is investigated. The present plate theory based on classical laminated thin with strain gradient effect take into account nonlocality nanostructures. equilibrium equations have been carried out by using principle virtual works a system partial differential sixth order has out, contrast fourth order. solution obtained trigonometric expansion (e.g., Navier method) which applicable simply supported boundary conditions limited lamination schemes. exact for loads; nevertheless, convergence be proved other load types such as one. Both schemes (cross-ply angle-ply nanoplates) are studied. Results reported dimensionless form validity methodology proven, when possible, comparing results ones from literature (available only cross-ply laminates). Novel applications shown cross- can considered further developments same topic.
