This module is not approved as a discovery module
ObjectivesThe objectives of this module are to:
- apply a quantitative treatment to the mechanical properties of materials, and their origin;
- provide the scientific basis for the relationship between materials properties and their microstructure;
- give students the necessary background to understand the design of suitable microstructures to give desired properties across the full range of materials classes;
- apply a knowledge gained of the processing-microstructure-property relationship to the design of alloys, ceramics, polymers and composites for structural applications;
- illustrate the state-of-the-art in these materials and show how research has, and continues, to inform the design of these materials.
At the end of this module, students should:
- understand the origins of elastic behaviour of solids and its relationship to structure;
- understand the principles of non-linear elasticity;
- understand the origin and application of linear elastic fracture mechanics to brittle fracture and fatigue crack growth;
- understand the macroscopic aspects of the deformation and failure of materials by fatigue and creep and perform simple calculations to predict the lifetime of a component subjected to fatigue or creep using data obtained from standard tests;
- understand the micromechanics of deformation and fracture in monolithic and composite materials, their relationship to structure, and the principles of microstructural engineering to control mechanical behaviour;
- understand the principles of physical metallurgy and their application in the historical development of metals and alloys to satisfy the needs of different industrial sectors;
- understand the process-microstructure-properties relationship in the design of ceramics, polymers and composite materials with an appropriate combination of properties to satisfy the needs of different industrial sectors;
- understand the traditional limitations on properties and how metallurgists and materials scientists may seek to circumvent these in the design of novel materials with an improved range of properties;
- be aware of current research developments in metallurgy and materials science in this sector and its potential impact on design and technology.
