Module Overview

This course covers the main concepts of fracture mechanics and fatigue, with emphasis on practical applications for metals, ceramics, polymers and composites. All topics are introduced from first principles and the emphasis is on developing a comprehensive understanding of concepts and techniques involved and a critical awareness of some of the current problems.

Prerequisites/Co-requisites

None

Module Aims

These are to:

•explore the deformation and fracture behaviour of a range of engineering materials under various loading conditions

•introduce the principles of linear-elastic and elastic/plastic fracture mechanics and demonstrate their application

•study the process of failure under fatigue loading (especially for metallic materials), the associated predictive techniques and their application

Learning Outcomes

Upon successful completion of the course and associated assessment package, students will be able to:

•demonstrate a systematic understanding of the deformation and fracture characteristics of a range of engineering materials and the associated material property data

•recognise situations in which the application of fracture mechanics to an engineering component is appropriate, to make calculations using relevant data and to understand the limitations of these calculations

Module Content

The course will explore the deformation and fracture characteristics of the principal classes of engineering materials under a range of different conditions and identify the relevance of the various fracture mechanics parameters to each of these classes, and to demonstrate the applicability of fracture mechanics in component design and lifeing. The course will be based around lectures and exercise classes. The course integrates lectures, supervised exercise classes and practical demonstrations
