Geometrically nonlinear theory of thin-walled composite box beams using shear-deformable beam theory [PDF]

, 2010
A general geometrically nonlinear model for thin-walled composite space beams with arbitrary lay-ups under various types of loadings is presented. This model is based on the first-order shear deformable beam theory, and accounts for all the structural ...

On triply coupled vibrations of axially loaded thin-walled composite beams [PDF]

, 2010
Free vibration of axially loaded thin-walled composite beams with arbitrary lay-ups is presented. This model is based on the classical lamination theory, and accounts for all the structural coupling coming from material anisotropy.

Continuous-Wave Molecular Modulation Using a High-Finesse Cavity

Applied Sciences, 2014
We demonstrate an optical modulator at a frequency of 90 THz that has the capability to modulate any laser beam in the optical region of the spectrum. The modulator is constructed by placing deuterium molecules inside a high-finesse cavity and driving a ...

Molecular nano-I-beam class of materials: options based on configuration, first principles-based optimization and properties

Scientific Reports
Nanotubes showed merits including high structural strength-to-weight ratio. However, tubes are less favored regarding stiffness and strength. Nano-I-beams are proposed for improved nano-mechanics.
