Pre-Requisites: | The equivalence of AMME9301 AND (AMME9302 OR CIVL9110) |
Brief Handbook Description: | This unit aims for students to understand the relationship between properties of engineering 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; oxidation and corrosion; friction and wear; Steel and non-ferrous alloys; structure-property relationships; selection of materials in mechanical design. |
Assumed Knowledge: | (1) A good understanding of basic knowledge and principles of material science and engineering from Materials I and mechanics of solids for simple structural elements (in tension, bending, torsion); (2) Reasonable mathematical skills in calculation of stresses and strains in simple structural elements. |

T&L Activities: | Tutorial: Tutorials are conducted twice a week for individual students. Tutorials are aimed to give you more examples in relation to the knowledge and theories discussed during lectures and to help you to address the key knowledge required for tackling your assignments. Laboratory: Each student is required attend only once during semester for a 3-hour lab class on Tuesday afternoon commencing in Week 3 in s152 ME Building on evaluating brittle fracture of glass plates using the concept of Linear Elastic Fracture Mechanics. |
Attributes listed here represent the key course goals (see Course Map tab) designated for this unit. The list below describes how these attributes are developed through practice in the unit. See Learning Outcomes and Assessment tabs for details of how these attributes are assessed.

Assessment Description: |
Lab report: Each student is required to attend a lab session in one afternoon and submit a written report. The schedule of the lab sessions will be tabled in week 3. Quizzes: An in-class quiz will be conducted in week 7 and week 13, respectively. Assignment: There are totally four assignments in the semester, (1) Assignment 1 [25%] with some practical problems on basic mechanical behaviour of engineering materials. (2) Assignment 2 [25%] on knowledge of failure analyses using failure and fracture criteria. (3) Assignment 3 [25%] on fracture and fatigue analyses of engineering materials, and (4) Assignment 4 [25%] on the exercises and the establishment of sound knowledge in fatigue, fatigue crack growth and creep analyses for engineering materials. Final Exam: 2hr, close book examination. |
