Module content

Indicative content includes


Introduction
Basic Stress Analysis and Mechanical Properties
Stress Intensity Factor and its use in Fracture Mechanics
Energetics Approach to Fracture
Limitations of Linear Elastic Fracture Mechanics 
Elastic/Plastic Fracture Mechanics
Fatigue
Fatigue Assessment of Welded Structures
Fracture of ceramics
Application of Fracture Mechanics to Polymers and Composites
Aspects of fracture of metals.

Methods of Teaching / Learning

The learning and teaching strategy is designed to introduce the principles of linear elastic and elastic-plastic fracture mechanics and to explain their relevance to solving engineering problems relating to crack propagation in structures under short-term and long term (fatigue, creep) conditions.  In doing this, the full range of engineering materials will be considered, with reference to a range of practical applications.

The learning and teaching methods include:


14 hours lectures
4 hours tutorial classes (all students)
3 hours tutorial classes (small group)
9 hours practical classes (3 hours design, 6 hours lab-based)
120 hours coursework .


The teaching is delivered as a one-week intensive course

Assessment Strategy

The assessment strategy:

Set of short questions covering the entire syllabus which require demonstration of a qualitative and quantitative understanding of underlying issues relevant to deformation and fracture of materials. Long questions require extensive research to identify and integrate information on a broad topic and recognition, analysis and solution of a complex problem using fracture mechanics methods.

Summative assessment and formative feedback


Q1 (4 x short answer) + Q2 (long answer question)


[Learning outcomes 1-5]        (45 hours)        Mon/Tues 2 weeks after end of course {40%}


Q3 (6 x short answer) + Q4 (long answer question)


[Learning outcomes 1-5]        (75 hours)        Mon/Tues 6 weeks after end of course {60%}


Formative verbal feedback is given in lectures and tutorials.
Written feedback is given on the first assessment coursework (Q1 & Q2), which is submitted in advance of the final summative assessment.
