Small scale effect on linear vibration of buckled size-dependent FG nanobeams

Ain Shams Engineering Journal, 2015
The thermal stress due to the temperature rise in micro/nano-beams with immovable ends produces compressive axial force which can lead to buckling the beams if its value increases over the critical value.

An alternative method for analysing buckling of laminated composite beams

Građevinar, 2017
In this study, two new functionals are derived based on Gâteaux differential in order to analyse buckling of symmetric cross-ply laminated composite straight beams. The functional comprises four independent variables, i.e.

Natural frequency of beams with embedded piezoelectric sensors and actuators

, 2007
A mathematical model is developed to study the natural frequency of beams with embedded piezoelectric sensors and actuators. The piezoelectric sensors/actuators in a non-piezoelectric matrix (host beam) are analyzed as two inhomogeneity problems by using

An efficient coupled polynomial interpolation scheme to eliminate material-locking in the Euler-Bernoulli piezoelectric beam finite element

Latin American Journal of Solids and Structures
The convergence characteristic of the conventional two-noded Euler-Bernoulli piezoelectric beam finite element depends on the configuration of the beam cross-section.

iso-spectral Euler-Bernoulli beams �� la Sophus Lie

, 2007
We obtain iso-spectral Euler-Bernoulli beams by using factorization and Lie symmetry techniques. The canonical Euler-Bernoulli beam operator is factorized as the product of a second-order linear differential operator and its adjoint. The factors are then reversed to obtain iso-spectral beams.
