Thermal conductance of buckled carbon nanotubes
Knowledge of thermal conductance of carbon nanotubes under mechanical deformation is important to characterize the robustness of carbon nanotube heat conduction. In this study, using molecular dynamic simulations, we have calculated thermal conductance of an elastically buckled single-walled carbon nanotube. A local buckle was formed by mechanically bending a carbon nanotube at an angle of 60°,...
متن کاملStretching of buckled filaments by thermal fluctuations.
We study the buckling instability of filaments or elastic rods in two spatial dimensions in the presence of thermal fluctuations. We present an analytical solution based on a renormalization-like procedure where we integrate out short wavelength fluctuations in order to obtain an effective theory governing the buckling instability. We calculate the resulting shift of the critical force by fluct...
متن کاملThermal Buckling Analysis of Circular FGM Plate with Actuator/Actuator Piezoelectric Layer Based on Neutral Plane
In this paper, the thermal buckling analysis of a circular plate made of FGM materials with actuator/actuator piezoelectric layers based on neutral plane, classical plate theory and first order shear deformation plate theory is investigated. Reddy's model is assumed for material properties of FGM plate. Plate under the thermal loading, nonlinear temperature rise through the thickness and clampe...
متن کاملChanging the Behavior of Parametric Resonance in Mems Oscillators by Tuning the Effective Cubic Stiffness
Nonlinearity plays a critical role on the behavior of oscillators operating in the parametric resonance mode. Here, we study the effects of Effective Nonlinear Parameter, (effective cubic stiffness), γ3eff, on the behavior of parametric resonance in a micro electro mechanical oscillator. The value of γ3eff can be tuned by changing the amplitude of applied voltage. Varying the sign of γ3eff can ...
متن کاملA Stiffness Estimator for Agonistic-Antagonistic Variable-Stiffness-Actuator Devices
Safe Physical Human Robot Interaction, conservation of energy and adaptability are just the main robotic applications that prompted the development of a number of Variable Stiffness Actuators (VSA). Implemented in a variety of ways, they use various technologies, and feature the most diverse mechanical solutions, all of which share a fundamentally unavoidable nonlinear behavior. The control sch...
