Module code: H7106
15 credits in autumn semester
Teaching method: Laboratory, Lecture, Practical, Workshop
Assessment modes: Coursework, Unseen examination
This module will cover topics including:
- approaching engineering problems from first principles
- the practice of formulating and modelling a problem and applying relevant concepts to describe and study system behaviour
- critical evaluation of solutions to engineering and design problems
- introduction to materials and material science: principal characteristics and applications of plastics, metals, composites, ceramics and natural materials
- historical and recent developments in material science with respect to design and engineering applications
- introduction to atomic and macroscopic level properties of materials
- key chemical, electrical, mechanical, thermal, environmental and manufacturing properties of materials
- how material properties arise from atomic level interactions
- atomic bonding
- the basic force/separation curve and the development of the stress/strain relationship
- introduction to behaviour of materials under load, introduction to forces and basic types of loading cases
- stress and strain curves
- mechanics of materials under axial tensile and compressive forces
- stress concentrations
- introduction to design stresses and factors of safety
- selection of materials: basic methods of material selection, use of software in material selection
- engineering failures: typical failure mechanisms of materials such as fatigue, creep, crack growth, and corrosion
- case studies of engineering failures with respect to material selection and design
- introduction to manufacturing processes: casting, moulding, forming, machining, joining, rapid manufacturing and 3D printing
- correct machine shop working practice and related health and safety considerations
- practical lathe or milling exercise to understand feeds and speeds, operation, parting off, surface finish, tool selection, and cutting fluids/coolants
- engineering tolerances
- cost of manufacture and materials, and related design considerations.
