Nonlocal shell model for elastic wave propagation in single- and double-walled carbon nanotubes
This paper investigates the transverse and torsional wave in singleand double-walled carbon nanotubes (SWCNTs and DWCNTs), focusing on the effect of carbon nanotube microstructure on wave dispersion. The SWCNTs and DWCNTs are modeled as nonlocal single and double elastic cylindrical shells. Molecular dynamics (MD) simulations indicate that the wave dispersion predicted by the nonlocal elastic c...
متن کاملAxisymmetric wave propagation on a conical shell
Equations are derived to describe the propagation of axially symmetric waves generated at the apex of a conical shell, taking into account he coupling between longitudinal and transverse waves. A form of approximate solution is proposed, based upon the Green's function for wave propagation on a fiat plate but containing several variational parameters, the number of which can be reduced to one i...
متن کاملParallelized Transient Elastic Wave Propagation in Orthotropic Structures
We discuss the parallelization of a Velocity-Stress FDTD (VS-FDTD) code for the simulation of the propagation of mechanical waves in three-dimensional microstructures. The C++ code has been parallelized using MPI making extensive use of the Blitz++ library for local computation. We present numerical results for pyramid shaped domains, representing the tip of a focusing lens, that we have obtain...
متن کاملVariational Principles for Buckling of Microtubules Modeled as Nonlocal Orthotropic Shells
A variational principle for microtubules subject to a buckling load is derived by semi-inverse method. The microtubule is modeled as an orthotropic shell with the constitutive equations based on nonlocal elastic theory and the effect of filament network taken into account as an elastic surrounding. Microtubules can carry large compressive forces by virtue of the mechanical coupling between the ...
متن کاملWave propagation analysis of magneto-electro-thermo-elastic nanobeams using sinusoidal shear deformation beam model and nonlocal strain gradient theory
The main goal of this research is to provide a more detailed investigation of the size-dependent response of magneto-electro-thermo-elastic (METE) nanobeams subjected to propagating wave, ...
