Category | Special Subjects | |
Elective, Credits | Elective 2credit | |
Syllabus Number | 1F303 |
In this course, the following topics are studied;
(1) Basic concept of the strength and fracture of materials
(2) Understanding of the different types of fracture such as yielding, brittle fracture, fatigue, creep, corrosion, and the interaction among them
(3) Unified concept on fracture, which pays attention to metals, ceramics, polymers and composite materials
(4) Basis of linear fracture mechanics
The objective of the course is to provide students with a basic understanding of strengthand fracture of materials.
Your overall grade in the class will be decided based on followings:
- Term-end examinination (60%)
- Mini tests in the class (25%)
- "Self-made resume" submitted in the 15th lesson (15%)
Feedback will be given by commentary of the mini tests during class.

Please review the foundation of materials science studied in "Engineering Material 1" and foundation of mechanics of materials studied in "Strength of Materials 1" before attending class.
Please read the relevant part of the textbook before each lesson. (1.5 hours)
Please review the important items you learned in class by using texts and notes. Please answer the exercises again. (1.5 hours)
As preparatory learning on the 15th lesson, the main points (regime) of the contents learned in the 1st to the 14th lesson are summarized into a designated paper of A4 size. This "Self-made resume" can be used in term-end examination.
Preparation other than above will be instructed in class.
The diagrams/tables will be presented by using a projector and explanations will be added on the blackboard. It is important to acquire the habit of noting important matters by the students. Handwritten notes can be brought with the "handwritten regime" at term-end exam.
