# Postgraduate Course: Finite Element Analysis for Solids (IMFSE) (PGEE10029)

 School School of Engineering College College of Science and Engineering Credit level (Normal year taken) SCQF Level 10 (Postgraduate) Availability Not available to visiting students SCQF Credits 12 ECTS Credits 6 Summary The finite element method (FEM) (also called finite element analysis or FEA) originated from the need to solve complex problems in solid mechanics. FEM is used to obtain approximate numerical solutions to a variety of equations of calculus. Today it is used in a wide range of disciplines. This course is an introduction to FEA as applied to elasticity problems in solid and structural mechanics. The mathematical equations are developed using the virtual work basis of FEM and this is used to develop equations for one, two and three dimensional elements. As FEA is a computational tool this course includes practical exercises using the commercial package ABAQUS. A number of tutorials involving hand calculations are provided to aid understanding of the technique. Course description L1 Introduction Course outline; areas of application of the finite element (FE) method; examples of some problems for which FE analysis has been used. L2 FE terminology and steps Introduction to FE terminology; steps of the analysis using an assumed displacement field approach for linear elastic analysis of structures. L3 Input to and Output from a FE program 1 Feeding a finite element program (ABAQUS) with geometric, physical and loading information. L4 Input to and Output from a FE program 2 Understanding and interpreting results from a FE program. L5 FE Modelling Introduction to plane stress, plane strain, axisymmetric, and plate bending problems; degrees of freedom; stress-strain and strain-displacement relations. L6 Virtual Work Basis of Finite Element Method: 1 Definition of generic displacements, body forces, nodal displacements, and nodal actions; displacement shape functions with simple examples; relating generic displacements, strains, and stresses to nodal displacements. L7 Virtual Work Basis of Finite Element Method: 2 Derivation of FE equilibrium equations using the virtual work principle; examples of derivation of stiffness and equivalent load vector for a two node truss element.
