Teaching Method
Outline:
Shock phenomenon is unique, because it is single and high-speed phenomenon. As it can provide non-equilibrium and extremely high temperature and high pressure field relatively easily, shock phenomenon often apply to engineering.
This lecture will start from fundamental impact phenomena, learned in fundamental physics and strength of materials classes. Then, fundamental theory, analysis and application for shock compression of solids, induced by hypervelocity impact, will be introduced. In latter part of this course, effect around explosion of high energy materials, such as high explosives, and mitigation of damages by the explosion will be discussed. As most of the materials are written in English, students can empirically learn how to read English materials.
Style:
The class consists of lecture, reading English materials, teaching each other, and solving exercises etc. Students are required to work on home work every week.
Notice:
A knowledge of college-level physics is a prerequisite for this lecture.
