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.

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
Basic Stress Analysis and Mechanical Properties
Stress Intensity Factor and its use in Fracture Mechanics
Fracture of Ceramics
Energetics Approach to Fracture
Limitations of Linear Elastic Fracture Mechanics
Aspects of Fracture of Metals

Application of Fracture Mechanics to Polymers and Composites

Methods of Teaching/Learning
Intensive five day teaching period including lectures, tutorials, problem solving and laboratory sessions, followed by assessment package of a nominal 120 hours work, to be submitted within six months (part-time) or six weeks (full-time) of the end of the course week.

Total student learning time 150 hours.
