Overview

The Finite Element Method (FEM) is one of the most powerful and versatile numerical methods for solving complex engineering and physical problems. Originating in structural mechanics, FEM has now become a fundamental technique applied in diverse fields such as thermal analysis, fluid dynamics, electromagnetics, and biomechanics. Its ability to handle complex geometries, boundary conditions, and material behaviours makes it indispensable for modern engineering analysis and design.This book, Finite Element Methods: Introduction and Concepts, aims to provide a concise yet comprehensive introduction to the fundamental principles and computational aspects of FEM. It is designed for undergraduate and postgraduate engineering students, as well as practising engineers and researchers seeking to deepen their understanding of this important technique.The text begins with the basic mathematical foundations and variational principles before progressing to one-, two-, and three-dimensional finite element formulations. Special emphasis is placed on the derivation of element equations, shape functions, and stiffness matrices, with step-by-step examples to enhance clarity.
