PREFACE to Boundary Elements Theory and Applications:

The final three many years have been marked by the evolution of digital computer systems and an infinite and wide-spread availability of computational energy.

This has boosted the event of computational strategies and their software in engineering and within the evaluation and design of constructions, which prolong from bridges to aircrafts and from machine parts to tunnels and the human physique.

New scientific subfields had been generated in all engineering disciplines being described as “Computational”, e.g. Computational Mechanics, Computational Fluid Mechanics, Computational Structural Evaluation, Computational Structural Dynamics and so forth.

The Finite Aspect Technique (FEM) and the Boundary Aspect Technique (BEM) are the most well-liked of the computational strategies.

Whereas the FEM has been lengthy established and is most well-known within the engineering neighborhood, the BEM appeared later providing new computational capabilities with its effectiveness, accuracy and low computational price.

Though the BEM is taught as a daily course at an ever growing variety of universities, there’s a noticeable lack of a textbook which might assist college students in addition to skilled engineers to grasp the tactic, the underlying concept and its software to engineering issues.

An important purpose is that BEM programs are taught primarily as superior graduate programs, and subsequently a lot of the underlying elementary data of arithmetic and mechanics will not be coated within the respective undergraduate programs.

Thus, the present books on BEM are addressed slightly to academia and researchers who, in some way, have already been uncovered to the BEM than to college students following a BEM course for the primary time and engineers who’re utilizing boundary aspect software program in trade.

This statement stimulated the writer to write down the guide at hand. His analysis within the improvement of BEM over the past 25 years in addition to the expertise he acquired by instructing for a few years the course of Boundary Elements on the Civil Engineering Division of the Nationwide Technical College of Athens, Greece, justify this endeavor.

The writer’s ambition was to make BEM accessible to the coed as properly to the skilled engineer. For that reason, his predominant job was to arrange and current the fabric in such a means in order that the guide turns into “userfriendly” and simple to understand, bearing in mind solely the arithmetic and mechanics to which college students have been uncovered throughout their undergraduate research.

This effort led to an modern, in lots of facets, means of presenting BEM, together with the derivation of elementary options, the integral illustration of the options and the boundary integral equations for numerous governing differential equations in a easy means minimizing a recourse to arithmetic with which the coed will not be acquainted.

The indicial and tensorial notations, although they facilitate the authors’ work and enable to borrow prepared to make use of expressions from the literature, have been averted within the current guide. Nonetheless, all the required preliminary mathematical ideas have been included to be able to make the guide full and self-sufficient.

In closing, the writer wish to specific his honest due to his former pupil and Visiting Assistant Professor at Texas A&M College Dr. Filis Kokkinos for his fastidiously studying the manuscript and his ideas for constructive modifications.

His critic and feedback are tremendously appreciated. Thanks additionally belong to my doctoral pupil Mr. G.C. Tsiatas, M.Sc., for checking the numerical outcomes and the derivation of a number of expressions.
