Learning Outcomes

Partial CEng Programme Level Learning Outcomes

Having successfully completed this module you will be able to:

• The service failure case studies that are assessed by a concise consultancy style report (case study) require a design recommendation to be developed for a non-technical layperson to understand
• Problem solving tutorials in materials and structures prepare the students for the final assessment problems based on the materials and structures knowledge and understanding learnt in the course
• Materials property variations linked to manufacturing issues and the link to quality assurance in specifying materials performance is assessed in the final examination
• The service failure case studies that are assessed by a concise consultancy style report (case study) require a design recommendation to be developed that considers customer needs, safety and some commercial issues, thus partly fulfilling this learning objective
• The laboratory classes include experimental measurements, testing and analysis associated with bending structures, fatigue evaluations and corrosion testing. The outcome will be assessed through submitted experimental reports.
• Materials selection discussion, and in service monitoring techniques form an integral part of the course assessments, in both coursework and examination form
• Materials and structures engineering knowledge and concepts are regularly assessed in the weekly coursework quizzes and integrated in the case study discussions (which feature some research outcomes from the lecturers’ research, applying this knowledge to case studies also then forms part of the final assessment)
• The service failure case studies are assessed by a concise consultancy style report (case study) which requires an assessment of the failure process that has occurred in service and the associated risks associated with the continued operation and/or maintenance of the components
• The structures laboratory based coursework includes a comparison of analytical, experimental and FEA calculations in bending exemplars which develops students’ understanding of when and how to apply computational and/or analytical approaches in structures assessments

Introduction to whole course: the interaction of materials and structures •Advanced topics in bending. •Fluctuating stresses and fatigue failure. Fatigue analysis for steady and •fluctuating loads (lectures, tutorial) •Advanced topics in torsion •Advanced topics in buckling. •Energy methods for stress and deformation analysis •Introduction to continuum mechanics •Structural Performance of Materials: Fracture, Fatigue, Wear and Corrosion: An introduction to the major failure modes and a consideration of the failure mechanisms. Methods to combat these failure modes are considered. Analysis of fatigue in engineering components subject to bending, tension and torsion. Lightweight materials: •Composites: Designing with polymer matrix composites with glass, Kevlar and carbon fibres. Basic composite theory, the properties and applications of composites. Manufacturing methods are described. Light •Metals: A comparison of the metallurgy and properties of the competing light metals - the alloys of aluminium, magnesium and titanium. The effect of heat treatment upon properties is considered. •Ferrous Alloys : Consideration of the properties, structures and the structural transformations which occur in ferrous alloys. Selection and use of steels for structural engineering applications. •High temperature materials: High temperature requirements, oxidation, creep, high temperature materials: nickel alloys and ceramics. Improving performance at high temperatures.

Teaching methods include: 1.Lectures on the topics covering the syllabus along with numerical example sheets as a part of the course material. 2.Problem classes and case study workshops. 3.Laboratory sessions on relevant topics to support the theoretical understanding. Learning activities include: Individual work on examples in the course material, attendance at laboratory classes, tutorials and associated coursework completion
