# FEEG6010 Advanced Finite Element Analysis

## Module Overview

This module is aimed at providing exposure to and understanding of advanced, specialist areas of Finite Element Analysis and their underlying Solid/Structural Mechanics concepts. It then concentrates on using this knowledge for solving discipline-specific engineering problems employing commercial Finite Element Analysis software.

### Aims and Objectives

#### Module Aims

- Provide complements of Solid and Structural mechanics required for the FEA contents. - Provide detailed understanding of using FEA to solve advanced structural and solid mechanics problems involving material nonlinearity. - Develop the ability to make informed use of a typical commercial FEA package to solve complex engineering problems. For Civil Engineering students: - Provide detailed understanding of using FEA to solve transient, coupled pore pressure-deformation (consolidation) problems and problems involving groundwater seepage. For Aeronautics & Astronautics, Mechanical Engineering and Ship Science students: - Provide detailed lems involving geometric non-linearity.

#### Learning Outcomes
