Analytical mathematical solution for vibrational response of postbuckled laminated FG-GPLRC nonlocal strain gradient micro-/nanobeams
TL;DR: An inhomogeneous beam model incorporating size effects is formulated based on the nonlocal strain gradient theory of elasticity within the framework of a third-order shear deformation beam theory to analyze the size dependency in vibration behavior of postbuckled laminated functionally graded (FG) micro-/nanobeams made from graphene platelet-reinforced composite.
Journal ArticleDOI
Small scale effects on buckling and postbuckling behaviors of axially loaded FGM nanoshells based on nonlocal strain gradient elasticity theory
TL;DR: In this article, a nonlocal strain gradient continuum theory is proposed to take small scale effects into consideration in a more accurate way, a non-local stress field parameter and an internal length scale parameter are incorporated simultaneously into an exponential shear deformation shell theory.
Journal ArticleDOI
Surface elastic shell model for nonlinear primary resonant dynamics of FG porous nanoshells incorporating modal interactions
TL;DR: In this paper, an analytical nonlinear primary resonance solution of functionally graded (FG) porous nanoshells under an external soft harmonic excitation including surface stress effects is presented.
Journal ArticleDOI
Nonlocal strain gradient beam model for nonlinear secondary resonance analysis of functionally graded porous micro/nano-beams under periodic hard excitations
TL;DR: FunctionFunctionally graded porous materials (FGPMs) have a wide range of applications as hollow members in biomedical and aeronautical engineering as mentioned in this paper. But the porosity is varied over the material v
Journal ArticleDOI
Finite element study on elastic transition in platelet reinforced composites
TL;DR: In this paper, an FEM model based on the Galerkin method for analyzing elastic stress field in a platelet reinforced composite subjected to axial load was developed and validated using analytical 3D and shear-lag models and ANSYS results.
