FEEG2005 Materials and Structures

Module Overview

This second year module continues to develop the links between structures and materials, building on the fundamentals established in the first year course on mechanics, structures and materials. The relationship between composition, microstructure and properties of materials is linked to a deeper understanding of their structural performance. This assessment of structural performance is also developed through more advanced stress and deflection analyses for more complex engineering components and systems. This combination of approaches will strengthen the students’ understanding of the interplay between materials engineering and structural design. This module also develops the foundations for more advanced third year and fourth year modules in materials and solid mechanics.

Aims and Objectives

Module Aims

- Introduce advanced methods for stress and deflection analysis of more complex engineering components and systems. - Develop and deepen knowledge already gained in FEEG1002 of the relationship between composition, microstructure and properties of materials in structural performance. - Establish a relationship between materials engineering and structural design. - Prepare students for higher level modules.
