Mechanics of Materials (9 lectures)

States of stress and strain at a point; analysis of stress under conditions of plane stress and plane strain; strain rosettes; generalised stress-strain relationships for linearly elastic and isotropic materials.


Bending of Beams (6 lectures)

Beams made of dissimilar materials. Asymmetrical or skew bending. Thin-walled open sections and shear centre.


Fracture in Brittle Materials (6 lectures)

Failure mechanisms in brittle materials. Introduction to linear elastic fracture mechanics; fracture toughness. Crack growth under repeated or cyclic loading.


Theories of Yield and Axisymmetric Systems (9 lectures)

Theories of yield. Characterisation of post yield properties for isotropic metals under uniaxial tension.

Stresses and strains in axisymmetric systems, including thick-walled pressure cylinders. Initial yield and plastic collapse in pressure vessels.
Composite Materials (6 lectures)

Elastic behaviour of anisotropic materials. Properties of fibre composite materials. Micromechanics – rules of mixtures, modified rules of mixtures. Short fibre composites.
