Module Aims
|
To make the students familiar with a range of modes of failure, with
particular emphasis on fracture, time dependent deformation mechanisms
and elastic failure of a simple component.
To introduce a method of selecting engineering materials which takes
into account requirements which may be conflicting, of different
relative importance or non mechanical (e.g. environmental) in nature.
|
Learning Outcomes
|
*On completion of this module, the student will be able to
Apply conventional engineering terminology and nomenclature to simple
material mechanics problems. (PO1, PO6)
Devise an appropriate calculation from a narrative describing component
loading and geometry. (PO1,PO2,PO3,PO6)
Calculate stress and strain in simple components under axial, or bending
loading.(PO1,PO2)
Assess likely failure mechanisms including fracture, corrosion, creep
and fatigue under a range of service conditions an interpret material
data in this context. (PO1, PO2. PO3)
Apply a systematic approach to the selection of a material (PO1, PO2, PO3)
Identify the phase of material lifecycle contributing most to
environmental impact, looking at extraction, useable lifetime and
disposal phases. (PO4)
