Mechanical behaviour and identification of damage by acoustic emission of smart composites

S. Masmoudi, A. El Mahi, R. El Guerjouma, S. Turki

The smaller sizes of current electronic devices suggest the feasibility of creating a smart composite structure using piezoelectric implant to monitor in-situ and in-service…

The flutter of truncated conical shell subjected to internal supersonic air flow

Zhang Ruili, Yang Zhichun, Gao Yang

The purpose of this paper is to propose a new approach to determine the aeroelastic instability of truncated conical shells. In the proposed approach the governing equation of…

Rheological behaviour and applicability of viscoelastic model for wave propagation in non-homogeneous polymer rods

Rajneesh Kakar, Shikha Kakar, Kanwaljeet Kaur

This purpose of this paper is to discuss certain aspects of five-parameter viscoelastic models to study harmonic waves in the non-homogeneous polymer rods of varying density…

Dynamics analysis of dual-axis positioning mechanism of satellite antenna with joint clearance

Zheng Feng Bai, Yang Zhao, Jun Chen

The existence of clearance in joints of positioning mechanism is inevitable and the movements of the real mechanism are deflected from the ideal mechanism due to the clearances…

Real time algorithm implemented in Altera's FPGA for a newly designed mobile robot: Autonomous navigation and parallel parking

Chokri Abdelmoula, Fakher Chaari, Mohamed Masmoudi

The purpose of this paper is to propose a generic platform for a robotic mobile system, seeking to obtain a support tool for under-graduation and graduation activities. Another…

FE modeling of creep in linear and non-linear FGM cylinder under internal pressure

Manish Garg, Dharmpal Deepak, V.K. Gupta

The purpose of this paper is to investigate creep in an internally pressurized thick-walled, closed ends cylinder made of functionally graded composite, having linear and…

Heat transfer of convective MHD viscoelastic fluid along a moving inclined plate with power law surface temperature using finite element method

Minakshi Poonia, R. Bhargava

The purpose of this paper is to deal with the study of free convection magnetohydrodynamic (MHD) boundary layer flow of an incompressible viscoelastic fluid along an inclined…

A modified Preisach model and its inversion for hysteresis compensation in piezoelectric actuators

Xuan Wang, Aurélien Reysett, Valérie Pommier-Budinger, Yves Gourinat

Piezoelectric actuators (PEAs) exhibit hysteresis nonlinearity in open-loop operation, which may lead to unwanted inaccuracy and limit system performance. Classical Preisach model…
