## COURSE OBJECTIVES

The course provides advanced knowledge on the application of finite element analysis to engineering applications in linear structural mechanics and heat transfer problems. The course analyses critically problems involving one, two- and three-dimensional idealizations. The topics covered include steps in finite element modelling process, behaviour of spring, truss, beam, plane stress/strain and three dimensional finite element modelling approaches in structural mechanics. The heat transfer part of the course examines the conduction and convection behaviour and analyzing these mechanisms using finite element analysis.
