Nonlinear buckled states of rectangular plates

Archive for Rational Mechanics and Analysis, 1974
A constructive method is developed to establish the existence of buckled states of a thin, flat elastic plate that is rectangular in shape, simply supported along its edges, and subjected to a constant compressive thrust applied normal to its two short edges.

Nonlinear buckling and post-buckling analysis of imperfect porous plates under mechanical loads

Journal of Sandwich Structures and Materials, 2018
The nonlinear buckling and post-buckling response of imperfect porous plates is investigated analytically in this paper. The porous materials with elastic moduli are assumed to vary through the thickness of the plate according to two different ...

Nonlinear Thermally Buckled Piezoelectric Energy Harvester

Volume 6: 12th International Conference on Multibody Systems, Nonlinear Dynamics, and Control, 2016
A thermally buckled piezoelectric energy harvester is designed to power biomedical devices inside the body. The energy harvester (EN) uses the vibrations inside the body to generate the electricity needed for powering biomedical sensors and devices. The piezoelectric beam consists of a brass substrate and two piezoelectric patches attached to the top ...

Buckling and geometrically nonlinear analysis of sandwich structures

International Journal of Mechanical Sciences, 2015
Abstract In this work a finite element model is presented for buckling and nonlinear analysis of multilayer sandwich plates and shells, with a soft core sandwiched between stiff elastic layers. The finite element is obtained by assembling all element-layers through the thickness using specific assumptions on the displacement continuity at the ...

Nonlinear Axisymmetric Buckled States of Shallow Spherical Caps

SIAM Journal on Mathematical Analysis, 1975
Nonlinear axisymmetric buckled states of a thin, elastic spherical cap satisfying edge conditions for which the spherical shape remains one possible state of equilibrium when the cap is subjected to a uniform radial load are studied by constructive methods.

Creep buckling of nonlinear viscoelastic columns

Acta Mechanica, 1986
Creep buckling of columns is analyzed for materials obeying nonlinear single memory integral constitutive laws. There have been two basic methods to analyze creep buckling of columns; the Rabotnov and Shesterikov's linearized dynamical approach and Hoff's quasistatic nonlinear approach, the former predicts critical buckling loads and the latter yields ...

Fiber-optic strain-displacement sensor employing nonlinear buckling

Applied Optics, 1997
A new class of intrinsic fiber-optic strain-displacement sensors based on the precisely controlled nonlinear buckling of optical fibers and the resulting optical bend loss is introduced. A multimode fiber version of the sensor is described that exhibits a sensing range convenient for many structural monitoring applications (
