| Description:
| Aims: To co-ordinate previous studies of structural materials, first by an introduction to the classes of engineering materials followed by consideration of merit indices, fracture, fatigue, creep and composite materials. Examination of the selection of materials for real engineering applications follows. Learning Outcomes: After taking this unit the student should be able to: After taking this unit the student should be able to: describe the various types of engineering materials, describe the overall process of engineering design, and the place in it of materials selection; deduce from standard test results the materials information required for design; analyse materials requirements and propose solutions to the selection problem in specified design situations. Skills: Facilitated - intellectual, practical, key. Content: Introduction to engineering materials. The design process; the designer and materials selection. Design aspects of elastic properties, strength and fracture toughness. Design procedures for creep in metals and plastics, extrapolation methods. Fatigue, master diagrams for design purposes, damage accumulation laws, application of fracture mechanics, designing against fatigue. Formalised procedures for materials selection, the limits of the procedures and derivation and use of merit indices. |
