Forensic engineering

Why do products fail? Inadequate materials, poor manufacturing or assembly methods, bad design – failure can arise at any stage, giving designers clues as to what failed, why, and how to avoid future failures. Using real case studies, this module examines the principles of good product design and assesses the significance of poor design on the development process. You will work with techniques for analysing product failure, including scientific and engineering tests and observation. You will investigate real catastrophic failures – the Challenger space shuttle, the Hindenburg and the Tay Bridge – and consider the role of design, manufacturing, materials and communications in these fatal disasters.

What you will study

Forensic engineering, which draws on many different disciplines, is of relatively recent origin as a subject in its own right. Product design lies at the heart of successful manufacturing, whether of cars and aeroplanes at one level of complexity, or ladders and bottles at a simpler level. Failure gives the designer a clear indication of what to avoid in order to improve quality. Any innovations made by the designer should be protected, either by patent or by registered design. One of the module’s central aims is to provide guidance for good product design before development, so that wasted effort during development is eliminated. Our approach is through case studies, many based on the authors’ own cases, others on historical catastrophes and failures.

Block 1 Introduction to forensic engineering uses case studies, many including polymeric materials, to develop the skills you need for the analysis of product failure.

Block 2 Failure of products and processes provides a ‘toolbox’ of techniques: observations, scientific and engineering tests that can be used to establish evidence of the causes of a failure in a metallic product or process. A casebook presents real cases drawn from over forty years of one forensic metallurgist’s work. Some take you step by step through an investigation and ask you to consider allegations of serious or criminal negligence.

Block 3 Catastrophic failures examines large-scale failures that have caused loss of life, including the Tay Bridge disaster (1879), the Challenger space-shuttle disaster (1985) and the airship Hindenburg (1937). The studies consider the roles of stress concentration in the design of critical components, poor manufacturing and poor design, material failures, and poor communications.

Block 4 Intellectual property matters considers protection of new designs and inventive concepts. It concentrates on the arguments used for understanding particular patents, and the precedents that lawyers use for assessing construction, infringement and validity. Case studies include trials in which imitators were successfully sued by means of patents, and cases of new designs that were challenged unsuccessfully because the patents were weak or did not define the inventive concept widely enough to catch the alleged infringing product.

Entry

The module is for engineers, managers and scientists who work in manufacturing industry, especially those who are engaged in product design or quality assessment and control. 

There are no entry requirements, but we do assume that you have already done some study, up to HNC, HND or bachelors degree level, in a relevant subject area, or have equivalent experience from your employment. 

If you are already an OU student we recommend that your previous study should include our undergraduate OU level 1 module Engineering the future (T174) (or the discontinued T173) and/or our level 3 module Structural integrity: designing against failure (T357)

You do need to have a reasonable standard of spoken and written English to study successfully with us. Poor language skills will make study more difficult, and it will take longer. The normal requirements for English language skills are explained on our website.

If you have any doubts about whether your level of English is good enough for you to study this module you may find it helpful to look at our Skills for OU Study site.

If you have any doubt about the suitability of the module, please contact our Student Registration & Enquiry Service.

Qualifications

T839 is an optional module in our:

Some postgraduate qualifications allow study to be chosen from other subject areas. These qualifications allow most postgraduate modules to count towards them. We advise you to refer to the relevant qualification descriptions for information on the circumstances in which this module can count towards these qualifications because from time to time the structure and requirements may change.

Regulations

Teaching and assessment

Support from your tutor

You will have a tutor who will be responsible for monitoring your progress on the module, marking and commenting on your written work and whom you can contact for advice and guidance. You can also communicate with fellow students via an online forum, which is moderated by a tutor.

Contact our Student Registration & Enquiry Service if you want to know more about study with The Open University before you register.

Assessment

The assessment details can be found in the facts box above.

You will be expected to submit your tutor-marked assignments (TMAs) online through the eTMA system unless there are some difficulties which prevent you from doing so. In these circumstances, you must negotiate with your tutor to get their agreement to submit your assignment on paper.

Professional recognition

The Open University is registered with The Institute of Quality Assurance (IQA), Institute of Materials (IOM) and The Institution of Occupational Safety and Health (IOSH), for professional recognition.

Distance learning

The Open University is the world's leading provider of flexible, high quality distance learning. Unlike other universities we are not campus based. You will study in a flexible way that works for you whether you're at home, at work or on the move. As an OU student you'll be supported throughout your studies - your tutor or study adviser will guide and advise you, offer detailed feedback on your assignments, and help with any study issues. Tuition might be in face-to-face groups, via online tutorials, or by phone.
