A Theoretical and Experimental investigation of Nonlinear Vibrations of Buckled Beams
… results. The nonlinear planar vibrations of a buckled beam around its first buckling mode shape are investigated. Frequency-response curves characterizing single-mode responses of the beam under a primary resonance are generated using both approaches and contrasted with experimentally obtained …

A Theoretical and Experimental Study of Nonlinear Dynamics of Buckled Beams
… the nonlinear responses of a clamped-clamped buckled beam to a variety of external harmonic excitations and internal resonances. We assume that the beam geometry is uniform and its material is homogeneous. We initially buckle the beam by an axial force beyond the critical load of the first …

Large 3-D Deflection and Force Analysis of Lateral Torsional Buckled Beams
… research on the force and deflection behavior of beams with rectangular cross-sections undergoing lateral torsional buckling. The large 3-D deflection path of buckling beam tips was closely approximated by circular arcs in two planes. A new chain algorithm element was created from …

Thermal Post-Buckling and Vibration Analysis of Thermally Buckled Antisymmetrically Laminated Beams Using a 20 DOF Finite Element
… post-buckling, and vibrations of thermally buckled composite beams including shear deformation. The beam element used has ten degrees of freedom at each node: axial displacement, transverse displacement due to bending and shear, twisting angle, inplane shear rotation and their derivatives …

Low-frequency vibrational energy harvesting at the micro and meso scale
… applications, such as the Internet of Things. A buckled beam-based MEMS device can harvest power from low frequency, low amplitude vibrations which has never been achieved by a micro-scale device. Due to the poor fabricated quality of the active piezoelectric material in the device, however, the …
