• EG-129 Critical Logic

  Mathematics is the primary tool of engineers and engineering, this module framing and solving of unstructured puzzles. The general objective is to increase the student's mathematical awareness and problem-solving skills by discussing a variety of puzzles.The course presents some problem-solving rules and covers issues of understanding the problem and the role of intuition in problem-solving activities. Further, some mathematical problem-solving principles are discussed and elements of modelling, constraint-processing, optimization, probability, statistics, simulation, pattern recognition, and strategy are introduced.

• EG-188 Engineering Analysis for Materials 2

  To provide additional grounding in engineering analysis methods for materials students. The module will cover the most important analytical tools and methods used in engineering and will relate these to common materials-related examples. The module will ensure the required grounding in methods and techniques for those who have not previously covered this area, or who are returning after a gap. It will also provide opportunities for extension to more complicated examples for those who have more prior experience.

• EG-294 Airframe Structures

  This module covers the fundamentals of linear elasticity and the stress analysis of the thin-walled structural components which are commonly employed in the design of modern wings and fuselages. In particular, the bending, shearing and twisting of thin-walled beams with open, closed or multi-cell cross-sections is studied in detail. The stiffening effect of stringers is investigated and end constraints are discussed. Numerous examples demonstrate the application of the theory. The module teaches the analytical skills, but also develops the students' feeling for thin-walled structures.

• EGH309 Advanced Materials

  This module will cover the detailed mechanical behaviour of both metallic alloys and fibre composites. It will start with a recap of tensile failure mechanisms, but extend to compression and shear failures. Fracture mechanics will then be introduced as applied to metallic materials and be extended to damage accumulation methods for composite materials. Creep, fatigue and impact will be covered as will the effects of elevated temperature and external environmental conditions.
