Kinematics

Nik Abdullah Nik Mohamed

Generally in continuum mechanics there are two different approaches of describing the motion of any material body, or more precisely motion of any material point representing a material body.

Numerical Investigation of Flow-Induced Vibration of a Cantilever Beam for a Piezoelectric Energy Harvester

Applied Mechanics and Materials (2012)

Mohammad Rasidi Rasani Jiyuan Tu Nik Abdullah Nik Mohamed

Flexible cantilever beams in channel flow loses its stability through a flutter mechanism at sufficiently high Reynolds number. This sustained transfer of flow work to cantilever beam oscillation could be extracted to generate electrical power, which may be utilized to power wireless sensors for structural health monitoring or supply additional power in unmanned or micro air vehicles. Such flexible beam system is known to exhibit some form of hysteresis, with super- and sub-critical velocities for onset of flutter, which may not be captured by current potential flow modeling. We present numerical simulation of a viscous, Navier-Stokes solver coupled to a cantilever beam, to capture this flutter velocity hysteresis. Numerical result under a linearly varying flow velocity shows an approximately 11% hysteresis, suggesting potential of present model for identifying more accurate boundaries of beam flutter. The prediction of cantilevered piezoelectric beam response under varying or unsteady flow velocities is necessary for reliable design of energy harvesting devices and warrants further experimental investigations.

Assessment of specific absorption rate reduction in human head using metamaterial

Science and Engineering of Composite Materials (2013)

Mohammad Rashed Iqbal Faruque Mohammad Tariqul Islam Nik Abdullah Nik Mohamed

Abstract In this paper, the specific absorption rate (SAR) reduction in human head with metamaterial attachment is calculated. The finite-difference time-domain (FDTD) method has been used to evaluate the SAR in an anatomically correct model of the human head. We designed the double-negative metamaterials by placing periodic array arrangement of split ring resonators (SRRs). By properly designing and tuning the structural parameters of SRR S , the effective medium parameters can be made negative at 900 and 1800 MHz band, as presented in this paper. Experimental results show that, with presence of resonators, SAR reduction in the human head is achievable. These results can provide useful insight into the design of safety-compliant mobile communication equipment.

Introduction

Nik Abdullah Nik Mohamed

Up to our humble knowledge, beside time and space our universe consists of energy and matter. As matters mostly take a form of materials, it then became a human's natural urge to study how these materials behave and how this behaviour relates with energy in the framework of space and space-time .
