学習・教育到達度目標 D-1 （設計・システム系，情報・論理系，材料・バイオ系，力学系を含む工学の基礎となる学問分野について，自主的かつ継続的に学習できる。）

Teaching Method

Outline:

The mechanical engineer must select from among a variety of materials the material that appears to be optimal. Even in strength design, which is a major part of mechanical design, as a student you will be performing calculations based on the material properties that have already been selected by the author of the text. But what exactly is the basis for that choice? We will teach you the basics of how to scientifically select materials from a myriad of materials, which is essential for today's engineers.

Style:

The first half of the course is about learning about various materials, so researching a wide range of mechanical materials is also an important part of the study.
The second half focuses on calculations and assumes mastery of mechanics-related subjects such as mechanics of materials. [30 hours of class time + 60 hours of self-study time]

Notice:

In order to standardize knowledge about materials, the first half will include lectures on materials other than steel materials. Furthermore, it is not possible to scientifically select materials simply by memorizing material properties. In the lectures, we will organize and utilize the knowledge necessary for strength design of mechanical structures (knowledge learned in machining and mechanics subjects), so even if you are not good at these things (even if you have missed credits), you will have the attitude to review them properly. is necessary.
