Fundamentals of Finite Element Analysis

Understanding how structures respond to external forces is critical for modern engineering design. This course provides a clear, conceptual introduction to Finite Element Analysis (FEA), breaking down complex mathematical theories into readable, step-by-step explanations. You will transition from having zero prior FEA knowledge to confidently understanding how structural problems are discretized, solved, and analyzed. You will learn the core mechanics of 1D bars, trusses, and beams, and discover how these foundational principles are applied in industry-standard simulation tools. Learn the core principles, terminology, and historical context of the Finite Element Method. Classify different element types, including 1D bars, trusses, and beam elements. Calculate nodal displacements, forces, and moments using simplified step-by-step mathematical workflows. Apply proper sign conventions for rotation, displacement, and forces at structural nodes. Explore the general procedure for setting up and running a structural simulation in ABAQUS. Discover modern trends in computational engineering, including automation and scripting basics. The course starts with foundational definitions and the history of structural analysis before guiding you through the manual calculation of one-dimensional bar and three-bar truss problems. You will then study the conceptual steps of setting up simulations and learn how to interpret structural analysis results. This text-based course is designed for engineering students, mechanical designers, and beginners who want a solid theoretical foundation in FEA without needing complex prerequisites.
