This textbook represents the Finite Element Analysis lecture course given to college students within the third yr on the Division of Engineering Sciences (now F.I.L.S.), English Stream, College Politehnica of Bucharest, since 1992.

It grew in time together with a course taught in Romanian to college students within the School of Transports, helped by the emergence of microcomputer networks and integration of the thing into mechanical engineering curricula.

The syllabus of the 28-hour course, supplemented by 28-hour tutorial and lab. lessons, was structured alongside the NAFEMS suggestions revealed within the October 1988 situation of BENCHmark.

The course represents solely an introduction to the finite component evaluation, for which we wrote easy stand-alone single-element packages to help college students in fixing issues as homework.

It’s adopted by a sophisticated course within the fourth yr at F.I.L.S., referred to as Computational Structural Mechanics, the place college students are supposed to make use of industrial packages.

In designing the course, our purpose was to supply college students able to:

(a) understanding the theoretical background, (b) appreciating the construction of finite component packages for potential modification and improvement, (c) working packages and assessing their limitations, (d) taking a indifferent view in checking output, and (e) understanding failure messages and discovering methods of rectifying the errors.

The course syllabus was restricted to 2D linear elastic structural issues. It has been discovered advantageous to divide the finite component evaluation into two elements.

Firstly, the meeting course of with none approximations (illustrated by frameworks) adopted by the true finite component course of which includes approximations.

That is achieved beginning with trusses, then with beams and airplane frames, and progressively coping with membrane and plate-bending parts. Stable parts and shells aren’t handled. Our goal was to make sure that college students have achieved:

(a) a familiarity in working with matrix strategies and growing stiffness matrices, (b) an understanding of worldwide versus native coordinate programs, (c) the abilty to make use of the minimal potential power theorem and digital work equations,

(d) the mapping from isoparametric house to actual geometrics and the necessity for numerical integration, (e) an perception in numerical methods for linear equation fixing (Gauss elimination, frontal solvers and so on), and (f) using equilibrium, compatibility, stress/pressure relations and boundary situations.

As a course taught for non-native audio system, it has been thought of helpful to breed as language patterns some sentences from English texts.
