Materials and Structures

Learning Outcomes

Subject Specific Intellectual and Research Skills

Having successfully completed this module you will be able to:

• Identify major failure mechanisms and relate to design/service conditions
• Identify regions of high stress and deformation in engineering components and systems, and predict failure by using traditional methods of stress analysis
• Critically analyse a situation involving materials and prepare questions to be answered by experts in the field

Learning Outcomes

Having successfully completed this module you will be able to:

• C1 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) C2 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 C3 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 C5 The service failure case studies that are assessed by a concise consultancy style report require a design recommendation to be developed that considers customer needs, safety and some commercial issues, thus partly fulfilling this learning objective C9 The service failure case studies are assessed by a concise consultancy style report 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 C12/M12 The three laboratory classes include experimental measurements, testing and analysis associated with bending structures, fatigue evaluations and corrosion testing. C13/M13 Materials selection discussion, and in service monitoring techniques form an integral part of the course assessments, in both coursework and examination form C14/M14 Materials property variations linked to manufacturing issues and the link to quality assurance in specifying materials performance is assessed in the final examination C17 The service failure case studies that are assessed by a concise consultancy style report require a design recommendation to be developed for a non-technical layperson to understand
