"Finite elements ("FE or FEA") is a numerical tool used for analyzing problems involving stress analysis, heat and fluid flow, resonance frequencies and mode shapes, etc. Irregular shaped domains, various materials can be incorporated. The book deals with a variety of topics in a manner that integrates theory, algorithms, modeling, and computer implementation. Many solved examples reinforce this pedagogy along with end-of-chapter problems, in-house source codes on multiple platforms, and a solutions manual for the instructor. Topics include energy and Galerkin approaches, equation solving with sparsity, elasticity, heat conduction and other scalar field problems, vibration and preand post- processing. The variety of topics dealt with enables the book to be used as a text in various engineering disciplines, at the senior-undergraduate or 1st year graduate level. The book can also serve as a learning resource for practicing engineers"
