Thermomechanical properties of graphene: valence force field model approach

, 2012
Using the valence force field model of Perebeinos and Tersoff [Phys. Rev. B {\bf79}, 241409(R) (2009)], different energy modes of suspended graphene subjected to tensile or compressive strain are studied.

Ripple Texturing of Suspended Graphene Atomic Membranes

, 2009
Graphene is the nature's thinnest elastic membrane, with exceptional mechanical and electrical properties. We report the direct observation and creation of one-dimensional (1D) and 2D periodic ripples in suspended graphene sheets, using spontaneously and

Quantum electromechanics: Quantum tunneling near resonance and qubits from buckling nanobars

, 2006
Analyzing recent experimental results, we find similar behaviors and a deep analogy between three-junction superconducting qubits and suspended carbon nanotubes. When these different systems are ac-driven near their resonances, the resonance single-peak,

Theory of Chiral Modulations and Fluctuations in Smectic-A Liquid Crystals Under an Electric Field

, 2000
Chiral liquid crystals often exhibit periodic modulations in the molecular director; in particular, thin films of the smectic-C* phase show a chiral striped texture.

Buckling of a sandwich beam with carbon nano rod reinforced composite and porous core under axially variable forces by considering general strain

Results in Engineering
Scientists have explored alternative reinforcements to improve the mechanical properties of composite structures in recent years due to the high financial and environmental costs associated with the synthesis of carbon nanotubes and graphene plates.

Effective medium theory of elastic waves in random networks of rods

, 2012
We formulate an effective medium (mean field) theory of a material consisting of randomly distributed nodes connected by straight slender rods, hinged at the nodes.

Plate girders with corrugated webs

Journal of Civil Engineering and Management, 2010
Especially for the main frames of single‐storey steel buildings the use of corrugated web beams, mainly with sinusoidal corrugation, has been increased very much during the last years.
