Aims
This module aims to:
• Equip students to understand failure processes: creep, environmentally controlled fracture and fatigue that limit the life of engineering structures and to acquire the knowledge that will allow them to make estimates and predictions of the life and reliability of engineering structures.
• Familiarise students with surface engineering principles underlying the phenomena of friction, wear and lubrication and the importance of their control in engineering practice, including the selection of materials for tribological applications (e.g. bearings), the application of surface engineering technologies and the recognition and solution of tribological problems.
• Develop a general understanding of corrosion processes and corrosion control. To appreciate the role of chemical thermodynamics and kinetics in corrosion control and how this influences the selection of materials for engineering structures.
Outline Of Syllabus
Creep: Strength and deformation of metals and alloys at elevated temperature. Creep failure and design against creep.
Fatigue: Low cycle and high cycle fatigue. Effect of stress concentrations. Fatigue crack growth rate. Manson-Coffin law, Miner’s rule, fatigue limits.
Oxidation and corrosion: Oxide growth mechanisms; oxidation kinetics; Pilling-Bedworth ratio. Oxidation-resistant materials and coatings. Aqueous corrosion and corrosion control. General and localized corrosion, environmentally assisted failure to include corrosion fatigue, embrittlement and stress corrosion cracking of engineering materials with practical examples.
Introduction to tribology. Surface topography: roughness, real and true area of contact. Contact mechanics: Hertz theory and materials responses to contact stresses. The plasticity index. Friction processes: ways of controlling friction. Wear mechanisms, the Archard equation. Ways of ameliorating wear. Surface contact fatigue. Surface engineering: techniques and examples of applications. Lubrication regimes.

Teaching Activities
| Category | Activity | Number | Length | Student Hours | Comment |
|---|---|---|---|---|---|
| Scheduled Learning And Teaching Activities | Lecture | 20 | 1:00 | 20:00 | PiP sessions |
| Guided Independent Study | Assessment preparation and completion | 1 | 30:00 | 30:00 | Assessment preparation and completion |
| Scheduled Learning And Teaching Activities | Small group teaching | 6 | 1:00 | 6:00 | PiP tutorials |
| Guided Independent Study | Independent study | 1 | 44:00 | 44:00 | Review lecture notes and recommended texts as appropriate |

Teaching Rationale And Relationship
The PiP lectures are designed to help the student in the acquisition of a knowledge base that will facilitate understanding of creep, fatigue, wear and corrosion of materials.
Tutorials will enable students to practice analysis of systems and predict failures.
Private study will strengthen their knowledge base and enable students to tackle the calculations and problems.
Plan B: In case of Covid-19 disruption:
• PiP lectures will switch to non-synchronous online learning (lecture material in Canvas)
• PiP tutorial sessions will switch to synchronous online learning (delivered via Zoom)
Assessment Methods
The format of resits will be determined by the Board of Examiners
