Finite element methods for engineers
The advent of high-speed electronic digital computers has given tremendous impetus to all numerical methods for solving engineering problems. Finite element methods form one of the most versatile classes of such methods, and were originally developed in the field of structural analysis. They are, however, equally applicable to continuum mechanics problems in general, including those of fluid mechanics and heat transfer. While some very sophisticated finite element methods have been devised, there is a great deal of very useful analysis that can be performed with the most straightforward types, which are simple to understand and formulate.
The teaching of finite element methods has hitherto been largely confined to university postgraduate courses, particularly those concerned with structural analysis in civil or aeronautical engineering. The purpose of this book is to serve as an introduction to finite element methods applicable to a wider range of problems, particularly those encountered in mechanical engineering. The main emphasis is on the simplest methods suitable for solving two-dimensional problems. Since computer programs form an integral part of the finite element approach they are treated as such in the text. Several programs are presented and described in detail and their uses are illustrated with the aid of a number of practical case studies.
