MECH9362: Materials 2

This unit aims for students to understand the structure and properties of engineering materials, and how these can be controlled in processing according to product design. The course provides a practical and theoretical introduction to the recent development of advanced manufacturing and the role of engineering materials in it. At the end of this unit students should have the capability to select proper materials for engineering design by considering emerging manufacturing technologies including additive manufacturing. Course contents will include: metal, polymers and polymer composite materials; introductory advanced manufacturing; the processing-structure-property relationships; selection of materials for advanced manufacturing in mechanical design.

Mechanics of solids: statics, stress, strain

At the completion of this unit, you should be able to:

  • LO1. graph simple equations representing material props, interpret graphs and communicate the outcomes
  • LO2. design simple engineering structural elements such as beams and thin-walled structures against plastic yielding, brittle failure, creep rupture and brittle fracture and fatigue with the concept of damage tolerance using the basic principles in materials selection
  • LO3. design a simple engineering structure by applying both criteria against plastic yielding and brittle fracture
  • LO4. evaluate fatigue failure in terms fatigue plot (S-N curve) and crack growth based on a fracture mechanics approach (stress intensity factor range)
  • LO5. analyse rupture life of stead-state creep as a function of stress and temperature
  • LO6. understand the processing-structure-property relationships of advanced engineering materials such as composite materials and high performance alloys
  • LO7. understand the general relationship between materials micostructure and mechanical properties (e.g. modulus of elasticity, yield strength, fracture toughness, fatigue, creep resistance, friction and wear)
  • LO8. characterize mechanical behaviours of materials including basic mechanical property, fracture, fatigue and creep resistance.
