Mechanical Behaviour of Materials is the subject of semester IV of Anna University B.E Material Science And Engineering Syllabus. In this article, we are glad to provide the syllabus of the mechanical behaviour of materials part of Semester IV Subjects in the first-year course.
We intend to provide the subject code ML3403 – Mechanical Behaviour of Materials syllabus based on regulation 2021 by Anna University. You can get an idea of the topics in the syllabus of the mechanical behaviour of materials. We hope that the absolute idea on the syllabus will assist the students in avoiding confusion of revision according to weightage. We also include required textbooks and references. If you require anything regarding the syllabus you can comment in the below section. Hope you like this information. Don’t forget to share.
If you want to know more about the syllabus of B.E. Material Science And Engineering connected to an affiliated institution’s four-year undergraduate degree program. We provide you with a detailed Year-wise, semester-wise, and Subject-wise syllabus in the following link B.E. Material Science And Engineering Syllabus Regulation 2021 Anna University.
Aim Of Objectives:
The main learning objective of this course is to prepare students for:
- Having an overview of elastic and plastic behaviour of materials
- Getting enlightened with the different strengthening mechanisms.
- Obtaining an insight into the types of fracture and mechanics of fracture.
- Interpreting the fatigue behaviour of materials.
- Having an insight on the high-temperature behaviour of materials.
