Carbon nanotubes have an important role in reinforcing nanocomposits. Many experimental observations have shown that in the most nanostructures such as nanocomposites, carbon nanotubes (CNTs) are often characterized by a certain degree of waviness along their axial direction. In the present paper, the effects of initial curvature, influence of surrounding medium that is modeled as Winkler elast...

In this series of papers, we present a motion planning framework for planning comfortable and customizable motion of nonholonomic mobile robots such as intelligent wheelchairs and autonomous cars. In this first one we present the mathematical foundation of our framework. The motion of a mobile robot that transports a human should be comfortable and customizable. We identify several properties t...

Evaluation of soil-foundation-structure interaction (SFSI) effects on structural response is a challenging task because of the involved impact of uncertainties in system’s parameters and randomness in the input earthquake motion. In this paper, a rational method is utilized to elucidate these effects through the use of a rheological soil-foundation-structure model in a robust probabilistic simu...

Linear motors o er several advantages over their rotary counterparts in many applications requiring linear motion by eliminating mechanical transmission mechanisms. However, these advantages are obtained at the expense of added diÆculties in controlling such a system. This paper studies the high performance robust motion control of an iron core linear motor which is subject to signi cant nonlin...

In this paper, by using a resolvent operator technique of (H,η)monotone mappings, we study the behavior and sensitivity of the solutions of the system of parametric variational inclusions with (H,η)monotone operators in Hilbert spaces. Our results extend and improve the main results obtained by Agarwal, Huang and Tan [R. P. Agarwal, N. J. Huang and M. Y. Tan, Sensitivity analysis for a new syst...

Abstract The stability evaluation of the dams subjected to seismic excitations is really very complex as earthquake response concrete gravity dam depends upon its connection joints with foundation rock. This study presents considering welded contact and friction along dam-foundation rock interface. Friction provided using elements. Two-dimensional finite element model Oued Fodda dam, located in...

The use of intelligent nanocomposites in sensing and actuation applications has become quite common over the past decade. In this article, electro-thermo-mechanical nonlinear dynamic buckling of an orthotropic piezoelectric nanocomposite (PNC) cylindrical shell conveying viscous fluid is investigated. The composite cylindrical shell is made from Polyvinylidene Fluoride (PVDF) and reinforced by ...

In this paper, the nonlinear dynamic buckling of double-walled boron-nitride nanotube (DWBNNT) conveying viscous fluid is investigated based on Eringen's theory. BNNT is modeled as an Euler-Bernoulli beam and is subjected to combine mechanical, electrical and thermal loading. The effect of viscosity on fluid-BNNT interaction is considered based on Navier-Stokes relation. The van der Waals (vdW)...
