The Finite Element Method in Engineering by Singiresu S. Rao

The Finite Element Method in Engineering, Fifth Edition, provides a complete introduction to finite element methods with applications to solid mechanics, fluid mechanics, and heat transfer. Written by bestselling author S.S. Rao, this book provides students with a thorough grounding of the mathematical principles for setting up finite element solutions in civil, mechanical, and aerospace engineering applications. The new edition of this textbook includes examples using modern computer tools such as MatLab, Ansys, Nastran, and Abaqus.

This book discusses a wide range of topics, including discretization of the domain; interpolation models; higher order and isoparametric elements; derivation of element matrices and vectors; assembly of element matrices and vectors and derivation of system equations; numerical solution of finite element equations; basic equations of fluid mechanics; inviscid and irrotational flows; solution of quasi-harmonic equations; and solutions of Helmhotz and Reynolds equations. New to this edition are examples and applications in Matlab, Ansys, and Abaqus; structured problem solving approach in all worked examples; and new discussions throughout, including the direct method of deriving finite element equations, use of strong and weak form formulations, complete treatment of dynamic analysis, and detailed analysis of heat transfer problems. All figures are revised and redrawn for clarity.

This book will benefit professional engineers, practicing engineers learning finite element methods, and students in mechanical, structural, civil, and aerospace engineering.

However, for a computer to solve these PDEs, numerical techniques have been developed over the last few decades and one of the most prominent today is the finite element method. The finite element method started with significant promise in the modeling of several mechanical applications related to aerospace and civil engineering. The applications of the finite element method are only now starting to reach their potential. One of the most exciting prospects is its application in coupled problems such as fluid-structure interaction, thermomechanical, thermochemical, thermo-chemo-mechanical problems, biomechanics, biomedical engineering, piezoelectric, ferroelectric, and electromagnetics.

The finite element method FEM is a numerical method for solving problems of engineering and mathematical physics. Typical problem areas of interest include structural analysis , heat transfer , fluid flow , mass transport, and electromagnetic potential. The analytical solution of these problems generally require the solution to boundary value problems for partial differential equations. The finite element method formulation of the problem results in a system of algebraic equations. The method approximates the unknown function over the domain. The simple equations that model these finite elements are then assembled into a larger system of equations that models the entire problem. FEM then uses variational methods from the calculus of variations to approximate a solution by minimizing an associated error function.

Theoretical Approach and Problem Solving Techniques

It comprises of three major streams namely Manufacturing, Design and Thermal. It has excellent facilities for carrying out theoretical and experimental research. The participants are requested to send a letter of motivation clearly stating why they are interested in this course. The selection of the candidates is based on their letter of motivation and their current status in teaching career. Preference will be given to candidates who wish to pursue doctoral studies in the future.

The course includes finite element discretisation via weak form formulation of various engineering differential equations. The main applications are 2- and 3-dimensional field problems in heat conduction and elasticity problems. Finite element formulations of fluid mechanics problem will also be addressed. Based on Mechanics I, II and some elementary knowledge about fluid flow, this course gives a detailed introduction to the finite element methods used for solving different field problems in engineering science and multiphysics domains, including structural, heat transfer as well as fluid mechanics problems. Formulation, understanding and practice of the finite element methods will be emphasized. Lectures and exercises. Lectures, exercises and examination papers will be given in English only.
