Investigation of thermal preloading and porosity effects on the nonlocal nonlinear instability of FG nanobeams with geometrical imperfection

, 2021
The aim of the present research is twofold. The first is to present a study on nonlinear thermo-mechanical bending and thermal postbuckling analysis of functionally graded (FG) porous perfect/imperfect nanobeam according to the nonlocal elasticity theory.

Dynamic Stability of Shallow Arches with the Geometrical Imperfections

2009 International Joint Conference on Computational Sciences and Optimization, 2009
The dynamic stability of the hinged-hinged sinusoidal shallow arch with geometrical imperfection under time wise distributed load is investigated in this paper. First, the nonlinear governing equation of shallow arch is derived from the d’Alembert principle and Euler-Bernoulli assumption.

Dynamic Instability and Resonances of Geometrically Imperfect Plates

Volume 1D: 16th Biennial Conference on Mechanical Vibration and Noise, 1997
Abstract The parametric resonance and other dynamic instabilities of a rectangular plate with initial geometric imperfections acted upon by parametric excitation have been investigated. The temporal equations of motion describing the non-linear behavior of these plates for large oscillations are solved using a direct integration. Results

Stability of Geometrically Imperfect General-View Shells

International Applied Mechanics, 2000
The authors discuss a numerical algorithm which allows to study the loading curves in order to find out the singular points which are the boundary and bifurcation points. As example the stability of a finite panel is studied with allowance for the form imperfection.
