PREREQUISITES
COURSE AIM
The aim of the course is to present the basic formulations of energy methods and their applications to strength of materials. Basic knowledge of the formulation of Finite Element Methods and practical experience of the use of FEM in structural analysis.
CONTENTS
Energy methods (35%)
Generalised forces and displacements, Maxwell-Betti's theorem, the theorems of Castigliano, minimum of potential energy and the Rayleigh-Ritz method for approximate solutions. Applications of these methods to analyses of structural problems including rods, beams and plates.
Matrix methods (10%)
Displacement formulation for structural mechanics. The relations based on equilibrium, compatibility and material behaviour are formulated in matrix form. Assembly and solution of the structural equations. Practical use of matrix methods in truss and frame structures.
The Finite Element Method (55%)
The finite element method based on minimum of the potential energy. Finite element formulations for in plane plates, plates, shells and solids. Practical use of a FEM code applied on structural problems including plane plates, plates, shells and solids.
TEACHING
The education consists of lectures, exercises and computer exercises. Participation in computer exercises are compulsory.
EXAMINATION
Fulfilled computer exercises and a written examination at the end of the course.
