MECH8362: Materials 2

This unit aims for students to understand the relationship between properties of materials and their microstructures and to improve mechanical design based on knowledge of mechanics and properties of materials. At the end of this unit students should have the capability to select proper materials for simple engineering design. Course content will include: short-term and long-term mechanical properties; introductory fracture and fatigue mechanics, dislocations; polymers and polymer composite materials; ceramics and glasses; structure-property relationships; selection of materials in mechanical design.

Code MECH8362
Academic unit Aerospace, Mechanical and Mechatronic
Credit points 6
Assumed knowledge:
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.

Unit outlines

Unit outlines will be available 2 weeks before the first day of teaching for 1000-level and 5000-level units, or one week before the first day of teaching for all other units.

There are no unit outlines available online for previous years.
