Unit Description and General Aims
This unit will serve as an advanced course in Finite Element Method. This unit introduces finite element methods for the analysis of solid and structural problems. Steady-state, transient, and dynamic conditions are considered. Finite element methods and solution procedures for linear analyses are presented using largely physical arguments. The assessments and projects involve the use of the general-purpose finite element analysis program. Applications include finite element analyses, modelling of problems, and interpretation of numerical results.
