Short Lecture Course
Failure Analysis & Fractography of Composites
Monday - Tuesday, 1st – 2nd March 2010
Dr Emile S Greenhalgh FIMMM CEng
Roderic Hill Building, Prince Consort Road, Imperial College London, UK
Composite failure analysis and fractography is a
growing discipline and has proved to be
invaluable for studying fibre reinforced polymer
composites. By interpreting the fracture surface
morphology, the source and sequence of fracture
can be determined. Failure analysis is a powerful
research tool for solving real engineering
problems and can deliver significant cost savings
to component development.
The aims of the course are:
• Familiarisation of the procedures for failure
analysis of composites
• Identification of the morphology of the
different fracture modes
• Application of the basic methodology to the
investigation of failed components
The course will last for 8 hours of lectures,
delivered over 2 days, with the course text
provided to the delegates.
Who should attend?
The course should appeal to delegates with a
basic knowledge of composites, together with a
modest understanding laminate analysis. It will be
suitable for delegates who are interested in
applying fractographic methods, or wishing to
expand their expertise in this field, or for more
senior personnel who have responsibility for such
Date Monday - Methodology and Tools for Failure Analysis (2 hours)
1 - Fibre Dominated Failures (1 hour)
- Delamination Dominated Failures (1 hour)
Tuesday - Fatigue Failures (30 minutes)
nd - Influence of Fibre Architecture (1 hour)
2 - Defects and Damage (1 hour)
- Case Studies (1½ hours)
Syllabus details - The following lecture topics will be given:
Methodology & Tools for Failure Overview of health & safety issues. General procedures for failure
Analysis analysis. Initial visual examination and NDE. Methods for photographing
fracture surfaces. Dissection. Verification of materials & construction.
Optical & scanning electron microscopy. Sequencing cracks. Reporting.
Fibre Dominated Failures Morphologies associated with unidirectional laminates under tension,
compression, flexure and in-plane shear. Intralaminar fracture. Tension,
compression and flexure in cross-ply laminates. Tension, compression
and flexure in multidirectional laminates.
Delamination Dominated Failures Generic fracture morphologies of matrix resins. Pure modes of fracture in
unidirectional laminates; mode I & mode II. Features characteristic of
mixed-mode (I/II) delamination. Delamination at multi-directional ply
interfaces. Delamination under mode III & mixed II/III.
Fatigue Failures Basic fatigue morphologies of bulk polymers. Failures associated with
interlaminar and intralaminar fatigue. Fracture morphologies associated
with translaminar fatigue.
Influence of Fibre Architecture Features particular to short-fibre composites. Fracture morphologies in
filament wound materials. Morphologies of fabrics; woven and NCFs.
Fractography of through-thickness reinforced materials (stitched and z-
pinned laminates). Fractography of 3D composites.
Defects and Damge Defects associated with constituents (fibres and matrix) and the
fibre/matrix interface. Lamina scale defects; manufacturing and in-service
environmental degradation. Morphologies associated with in-service
damage, such as that induced by impact.
Case Studies Failures due to overloading or design deficiencies. Failures due to
material and manufacturing defects. Failures due to in-service factors.
About the Lecturer
Emile S. Greenhalgh is a Reader at the Composites Centre at Imperial College London. Between 1987 and
2003, Dr Greenhalgh worked at RAE (now QinetiQ) in Farnborough in the Composite Structures Section,
conducting research on a broad range of aspects of polymer composites and has published over one hundred
reports and papers in this field. Upon joining RAE he was trained by David Purslow, one of the founders of
fractographic analysis of composites. Since then he has further developed the field of fractography, focusing
on delamination and damage tolerance issues. He has developed new methods for identifying crack growth
directions and failure modes in compression and delamination failure. Throughout his career he has used
fractographic analysis to underpin his research findings. He has initiated a European working group on
composites fractography, conducted numerous failure investigations and his expertise has led involvement in
high profile component failures (e.g. Formula One crashes) and as an expert witness in litigation cases.
Through this work, he is now one of the leading European experts on failure analysis of composites, and one
of a handful in the world. In September 2009 he published a book on Failure Analysis and Fractography of
