AIMS
This subject consists of three distinct and fundamentally related topics -
- An introduction to the fundamentals of materials science will be given on atomic structure and bonding, crystal structures and defects, elastic and plastic deformation, dislocations and strengthening and failured (fast fracture, fatigue and creep)
- The mechanics of materials section will extend the concepts of material mechanical behaviour by detailing elastic/inelastic behaviour and introducing the concepts of stress and strain analysis. Topics covered may include the definition of principal stresses, plane stress, plane strain, two-dimensional stress and strain analysis, torsion, pure bending, transverse loading, Mohr’s circle, failure criteria, inelastic behaviour, residual stress
- This subject will also provide an introduction to finite element analysis (FEA) and its application for stress-strain analysis. Particular emphasis will be placed on the fundamental mechanisms by which materials fail under loading.
INDICATIVE CONTENT
- Mechanics: the definition of principal stresses, plane stress, plane strain, two-dimensional stress and strain analysis, torsion, pure bending, transverse loading, Mohr’s circle, failure criteria, inelastic behaviour, residual stress.
- Materials: atomic structure and bonding, crystal structures and defects, elastic and plastic deformation, dislocations and strengthening and failure (fast fracture, fatigue and creep).
- Finite element analysis (FEA): FEA procedure, application of FEA to discrete systems and continuous bodies.
