Description This is a core module for all mechanically based engineering degrees. It underpins decisions made in design, and provides a foundation for more advanced analysis techniques and tools. | |||||||||||||||||||||||||||||||||||||||||
Learning Outcomes 1. Devise an appropriate calculation (using conventional engineering terminology and nomenclature) from a narrative describing component loading and geometry. 2. Explain the mechanisms of fracture, fatigue, corrosion, and creep, discuss relevent material properties and apply predictive equations. 3. Apply a systematic approach to the selection of a material, i.e. mathematically represent a mix of property requirements for particular applications and design goals, and then use material selection charts to identify a subset of suitable materials. 4. Incorporate into material choice tools consideration of the phase of material lifecycle contributing most to environmental impact. 5. Carry out calculations to find forces, moments, stresses and deflections for simple beam elements under point, distributed and moment loads. 6. Run an experiment, present and interpret data and commmunicate results verbally and in technical report formats | |||||||||||||||||||||||||||||||||||||||||
