 Kurzbeschreibung This course will introduce students to the fundamental concepts of the widely established Method of Finite Elements including element formulations, numerical solution procedures and modelling details. The course will also equip students with the ability to code algorithms (largely based on MATLAB) for the solution of practical problems in Infrastructure and Civil engineering. Lernziel The Direct Stiffness Method is revisited and the basic principles of Matrix Structural Analysis are overviewed.The basic theoretical concepts of the Method of Finite Elements are imparted and perspectives for problem solving procedures are provided.Linear finite element models for truss and continuum elements are introduced and their application for structural elements is demonstrated. The Method of Finite Elements is implemented on practical problems through accompanying demonstrations and assignments. Inhalt 1) Introductory Concepts Matrices and linear algebra - short review.2) The Direct Stiffness Method Demos and exercises in MATLAB & Commercial FE software3) Formulation of the Method of Finite Elements. - The Principle of Virtual Work - Isoparametric formulations - 1D Elements (truss, beam) - 2D Elements (plane stress/strain) Demos and exercises in MATLAB & Commercial FE software4) Practical application of the Method of Finite Elements. - Practical Considerations - Results Interpretation - Final Project where a Real Test Case is modelled and analyzed Skript The lecture notes are in the form of slides, available online from the course webpage Literatur Structural Analysis with the Finite Element Method: Linear Statics, Vol. 1 & Vol. 2 by Eugenio Onate (available online via the ETH Library)Supplemental ReadingBathe, K.J., Finite Element Procedures, Prentice Hall, 1996. Voraussetzungen / Besonderes Prior basic knowledge of MATLAB is necessary.
