## Introduction to Finite Elements in EngineeringThis work provides an integrated approach to finite element methodologies, combining sound theory, examples and exercises involving engineering applications and the implementation of theory in complete, self-contained computer programs. This edition introduces new material on many topics, including frontal method, conjugate gradient method, orthotropic materials, Guyan reduction, three dimensional frames, least squares fit for quadrilateral element, two dimensional fins and von Mises stress. It prepares BASIC programs to work efficiently in the QBASIC environment available on DOS 5.0 or higher, and provides FORTRAN and C versions of all programs in a separate directory for easy access. All programs have been revised to work with file input, and new programs introduced that deal with multipoint constraints involving two variables. The book also introduces temperature effect in 1D, 2D, and 3D deformation and stress analysis programs, as well as frontal method in the hexahedral element for 3D analysis in HEXAFNT. The DATAFEM program has been revised to simplify data entry, and colour contour lines are now available in the CONTOUR1 program as well as contour bands in CONTOUR2. |
