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 Course Aims 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 Course structure 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 practitioners. Outline programme Date Monday - Methodology and Tools for Failure Analysis (2 hours) st 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 Polymer Composites. GENERAL COURSE INFORMATION How to register?
