Graduation Thesis 2

In Graduation Research 2 in the Material Strength Laboratory, research is conducted on material strength, especially on assessments of strength and property on mechanical fastening technology. Research contents are set individually, and research with novelty and originality is performed.

The purpose of Graduation Research 2 in the Material Strength Laboratory is to develop problem-solving skills through research. Specifically, we discover and set issues and problems that arise in conducting research, examine methods to solve them, and design and manufacture equipment as needed. In addition, the ability to solve problems is cultivated by logically analyzing and analyzing the acquired experimental results.

1. To be able to find and set issues and problems that arise in research.
2. To be able to find problems to solve problems and problems that arise in research, and design and manufacture equipment as needed.
3. To be able to solve the problem by analyzing and analyzing the experimental results logically.
