The book is presented in two Parts. Part I describes boundary element treatments of problems of the potential type, using both constant and quadratic boundary elements.

Introduction to Nonlinear Finite Element Analysis Introduction to Nonlinear Finite Element Analysis by N. Kim The objective of this textbook is to simply introduce the nonlinear finite element analysis procedure and to clearly explain the solution procedure to the reader. In contrast to the traditional textbooks which treat a vast amount of nonlinear theories comprehensively; this textbook only addresses the representative problems, detailed theories, solution procedures, and the computer implementation of the nonlinear FEM. Especially by using the MATLAB programming language to introduce the nonlinear solution procedure; those readers who are not familiar with FORTRAN or C++ programming languages can easily understand and add his/her own modules to the nonlinear analysis program.

Over the last decade, there has been an increased awareness of the benefits of employing Object-Oriented (OO) design and methodologies for development of software. Among the various languages available for OO development, Fortran 95 has some clear advantages for scientific and engineering programming. It offers features similar to other OO languages like C++ and Smalltalk as well as extensive and efficient numerical abilities. This paper will describe the OO design and implementation of P-adaptive finite element analysis (FEA) using Fortran. We will demonstrate how various OO principles were successfully employed to achieve greater flexibility, easier maintainability and extensibility.

This is helpful for a complex program like an adaptive finite element implementation. • Previous article in issue • Next article in issue.
