The objective of the course is to teach students the basic principles of the FEM and the procedures to do the structural analysis by using the FEM. The basic principles of the FEM include the formulations of the stiffness equation for various elements, the formulation and solution method of the global stiffness equations of the structures, etc. Through the course study, the students could perform stress analysis of simple structures; lay a foundation for complex structural analysis as well as for theoretical and applying research on the FEM.
