Preface

The book you are currently holding contains the Proceedings of the 3rd WSEAS

International Conference on APPLIED and THEORETICAL MECHANICS

(MECHANICS'07) which was held in Puerto De La Cruz, Tenerife, Canary Islands,

Spain, December 14-16, 2007

Mechanics is an “old science” with great history and with impact in all the other

scientists. However, nowadays Mechanics is one of the most important and modern

disciplines. New theories, new theoretical problems together with several modern

fascinating applications in Eleasticity, Plasticity, Fracture, and Damage Mechanics,

Mechanics of Nanomaterials, Fluid-Structure Interaction, Geomechanics and

Mechanics of Granular Materials, Damage Identification and Non Destructive

Evaluation (NDE), Micro Electromechanically Systems, Transport Phenomena in

Micro/Nanoscale, Biomechanics and Biomaterials, Aerodynamics and

Aeroelasticity, Advanced Materials and Smart Structures, Heat and Mass Transfer,

Flows in Porous Media, Mechatronics etc is now of fundamental importance to our

civilization.

The WSEAS Working Group on Mechanics initiated several conferences on Applied

and Theoretical Mechanics during last years. Also, the WSEAS WG on Mechanics

sponsors the conference: CONTINUUM MECHANICS, that will be organized in the

famous University of Cambridge (UK) in February of 2008 and also in February of

2009. You are invited to contribute to these events. For those that their research is

more applied, we strongly recommend: the conference on ENGINEERING

MECHANICS, STRUCTURES, ENGINEERING GEOLOGY (EMESEG '08)

Crete Island, Greece, July 22-24, 2008

www.wseas.org/conferences/2008/greece/emeseg

Some other conferences on Fluid Mechanics, Aerodynamics, Heat and Mass Transfer

can be found on the WSEAS Site: www.wseas.org

The Plenary Speeches of MECHANICS'07 were:

Upon modeling and testing of hand-arm system vibrations in the

view of professional diseases prevention

A systematic approach

Professor Simona Lache

University Transilvania of Brasov

Dept. of Precision Mechanics and Mechatronics

29 B-dul Eroilor, 500036 Brasov, Romania

Abstract: The paper presents the systematic approach regarding the modeling and

testing methods used for hand-arm system vibrations in the view of professional

diseases prevention. It aims to evaluating preventive strategies to reduce worker

exposures to hand-arm transmitted vibration and to decrease the occurrence of Hand-

Arm Vibration Syndrome (HAVS) in workers.

Special emphasis is given to preventive measures and to the transfer of knowledge

from the research results to tool manufacturers, and occupational health physicians in

fields related to medical, ergonomic, testing, engineering and legal aspects of HAVS.

Due to the importance of the subject, the European Directive 2002/44/EC has been

implemented into the national legislation of Member States.

Application of boundary element method to mixed boundary-value

problems of linear elastostatics

Professor Necla Kadioglu

Division of Mechanics, Civil Engineeering Department

Faculty of Civil Engineeering

Istanbul Technical University

TURKEY

Abstract: In this lecture, a summary will be introduced to solve the plane problems of

linear elasticity by reciprocal theorem for linear elastic materials. This method gives

an integral equation which will be solved numerically. This integral equation is the

starting point of the boundary element method. Here, both first boundary value

problems and mixed boundary value problems will be considered. Instead of classical

application of reciprocal theorem, and artificial boundary will be defined to eliminate

the singularities of the integral equation. Besides, an algorithm is added to calculate

multi-valued arctan function which arises during the integration of the kernels of the

integral equation mentioned above. The solution of a first boundary-value problem

with a multiply connected region has also been explained using this method. The main

goal is to calculate the unknowns of the problem on the boundary. For a first

boundary-value problem these unknowns are the displacement components on the

boundary. For a mixed boundaryvalue problem, unknowns are the displacements

components one part of the boundary and surface traction components on a second

part of the boundary. After finding boundary values for any problem the inner values

of displacement and stress components can be calculated using reciprocal theorem

without any singularity problem. But, to find the unknown stress component is also

possible with some restrictions on the boundary.

Control Solutions against Nonlinearities and Uncertainties in MEMS

Professor Ahmet Kuzu

TUBITAK (Turkish Scientific and Technological Research Council)

MAM (Maramara Research Center)

BTE (Institute of Information Technologies)

TURKEY

Abstract: In this paper, a summary of nonlinearities and uncertainties common in

most MEMS systems is discussed and control solutions are suggested against such

problems. MEMS structures have some nonlinearities because of the nature of

electrostatic force, couloumb friction and elasticity. Moreover, MEMS processes also

include high tolerances which cause high uncertainties in structural parameters, such

as dimension of beams, and physical parameters, such as viscosity friction

coefficients, which all affect system response. Hence, robust control techniques, i.e.

sliding mode control and nonlinear H-inf control, could be quite effective in the

control of MEMS devices, by providing rejection against matched nonlinearities and

uncertainties. In this study, firstly nonlinearity sources and tolerance effects in MEMS

are discussed. Next, the system performance with classical control techniques is

studied. Finally, several robust nonlinear techniques are developed to this aim, and

system performance under robust methods are compared with that obtained with

classical control methods.

Scaled boundary finite element method and soil-structure

interaction: coupled consolidation dynamic analysis of fully saturated

soils

Professor Mahmoud A. H. Hassanen

Director of the Undergraduate Studies

Architectural Engineering Programme Manager

Department of Civil Engineering,

Strathclyde University,

John Anderson Building,

107 Rottenrow,Glasgow G4 0NG

United Kingdom

Abstract: Biot's three-dimensional (3D) coupled consolidation theory can be

incorporated into the scaled boundary finite element method to enable dynamic soil-

structure interaction in fully saturated poroelastic media to be modelled. The detailed

formulation governing the general 3D time-dependent soil-structure interaction case is

considered for both bounded and unbounded media, in static and dynamic situations.

We would like to thank all members of the organizing laboratories for their

contribution to the organization of the conference.

The contents of this Book are also published in the CD-ROM Proceedings of the

Conference. Both will be sent to the WSEAS collaborating indices after the

conference: www.worldses.org/indexes.

In addition, papers of this book are permanently available to all the scientific

community via the WSEAS E-Library.

Expanded and enhanced versions of papers published in these conference proceedings

are also going to be considered for possible publication in one of the WSEAS journals

that participate in the major International Scientific Indices (Elsevier, Scopus, EI,

Compendex, INSPEC, CSA .... see: www.worldses.org/indexes) these papers must be

of high-quality (break-through work) and a new round of a very strict review will

follow. (No additional fee will be required for the publication of the extended version

in a journal).

We cordially thank all the people of WSEAS for their efforts to maintain the high

scientific level of conferences, proceedings and journals.
