Assessment Description: Research project and seminar: Each student is required to undertake a design project over a period of 7 weeks investigating the the structure-property relationship of a particular engineering material, and then to deliver their findings in a 10 minute presentation. The schedule of presentations will be tabled in week 3.

Quiz: An in-class quiz will be conducted in week 7.

Assignments: There are totally three assignments in the semester, and each is completed using the individual efforts. (1)Assignment 1 [30%] consists of some basic and practical problems where you practise your knowledge in mechanical behavior of engineering materials. (2)Assignment 2 [35%] aims to help comprehend deep knowledge in fracture and fatigue analyses of engineering materials. (3)Assignment 3 [35%] focuses on the exercises and the establishment of sound knowledge in fatigue, fatigue crack growth and creep analyses.

Final Exam: Final examination.
