Summary of Content

This module aims to introduce advanced concepts in Engineering Design and Structural Integrity Assessment for Mechanical Engineering students. Failure Analysis techniques: An analysis and understanding of potential failures helps designers focus on and understand the impact of potential process or product risks and failures. Supporting this area are advanced analysis skills in fatigue, creep and placticity. To understand failure, recognition of fracture surfaces is paramount. Techniques to monitor stress and strain will be addressed including Photoelastcity and Strain gauges. Innovation in design is most likely to be realised through the use of novel materials applications. Here, composites are likely to play a significant role. The module will give understanding to modern fibre reinforced composites (frp) and an appreciation of design implications in relation to engineering structures. Classical Lamination Theory will be extended from traditional shell theory. Summary of how PRME-related issues / topics are covered in this module : The principle of sustainability will be reinforced through the contextualisation of the subject matter is a common theme across all modules in the programme. Students will be encouraged to consider how the underlying physical principles affect their design decisions and the sustainability of their designs.

Learning Outcomes

On successful completion of this module the students should be able to:1. have a critical understanding of a range of spealised theories and concepts to assess structural integrity2. systematically quantify the effects and impacts of failures3. be able to recognise different failure surfaces4. design and analyse composite frp structures5. be able undertake practical stress anlysis techniques to monitor structure integrity

Teaching / Learning Strategy

The material covered during lectures will be reinforced and consolidated through tutorials, seminars and practical laboratory work. Students will study and solve real world engineering problems encouraging divergent thinking and broader, deeper learning. Students will take part in practical laboratory work which will enhance data acquisition and manipulation skills, individual and group working skills, technical report writing skills and communication skills in general. Through the use of the managed learning environment GCU Learn, students will become more engaged, flexible and independent in their learning as there will be a wide range of learning resources available on line. In addition to the core module content, links to relevant databases for the sourcing of additional reading material from the current research in the subject area from around the world, and notices regarding relevant professional body talks in the local area will be made available. The assessment of the students will incorporate laboratory and design and analysis work based on real world engineering problems through group and individual coursework, and an examination. Students will receive individualised feedback on their performance through one-to-one contact with tutors at tutorials and seminars and marked coursework, which will reinforce the students' learning, and examination results.
