FINITE ELEMENT METHOD (FEM) A numerical method commonly employed for obtaining approximate solutions to a wide variety of problems in engineering and mathematical physics. (Typical) Course objectives of FEM: To describe the concept and fundamental theory of the finite element method. To apply the method to sample problems in engineering mechanics. To give overall view of the method to enable participants to further apply the method for advanced topics of interest. 3
FINITE ELEMENT METHOD (FEM) The basic premise of the method is that a solution region can be analytically modeled or approximated by replacing it with an assemblage of discrete elements. At the end of this introductory course, participants should be able to: identify problems that could be solved using FEM select solution region, quantify applied load and boundary conditions list steps in solving structural problems using FEM interpret modeling results of FEM 4
Course Content: INTRODUCTION AND PROGRAM OVERVIEW A OVERVIEW OF FEM Modeling, concept of numerical experiment, requirements, modeling capabilities, engineering examples.
