Material science:
Recognition of micro-structural characteristics and composition of metals, ceramics, polymers and composites: Grain structure, lattice structure, slip planes and their effect on properties of parent material. Alloying elements and their effects. Crystallinity, polymerization, co-polymerisation; additives, cross-linking. 

Manufacturing:
Mechanical processing and the effect on structure and properties illustrated by a range of processes e.g. mechanical working of metals, powder processing of metals and ceramics, extrusion and forming of polymer sheet, welding, use of adhesives; effect of processing on structure and properties e.g. residual stresses, work hardening. Liquid processing: metal casting and injection moulding/extrusion of polymers; effect of processing on structure and properties e.g. grain structure, porosity. Treatment processes: heat treatments e.g. quench and precipitation hardening processes, glass transitions; surface treatments/surface engineering, polymer treatments, composites/powder produced materials, matrix/reinforcement relationships. Materials testing to determine the properties of commonly used engineering materials, such as mechanical strength, hardness, toughness, fatigue and creep resistance, corrosion and reactivity, wear resistance, optical and thermal properties and formability. 
Causes of failure: failure of material categories (metals, ceramics, polymers and composites) e.g. creep, fatigue, S-N curves; modification factors due to geometric, surface and environmental factors. Impact, overstressing, corrosion, temperature, thermal cycling, residual stresses, stress relaxation, degradation (composition change), radiation, electrical breakdown, or combinations of these. Protective systems and design against corrosion.

Basic mechanics:
Engineering designers, no matter from what background, need to acquire a fundamental appreciation of the mechanical and electrical principles that underpin the design and operation of a large range of products, engineering equipment and systems. This section will develop students&#39; understanding of the key mechanical concepts that relate to all aspects of engineering design. In particular, students will study elements of engineering statics including the analysis of beams, columns and shafts. They will then be introduced to elements of engineering dynamics, including the behavioural analysis of mechanical systems subject to uniform acceleration, the effects of energy transfer in systems.

Applied mathematical theory:
Engineering units. Algebraic functions. Fundamentals and notation of calculus (Gradient, rate of change, area beneath a function). Plotting and interpreting data in graphical formats. Trigonometry and geometry. Scalars and vectors.
