Course Objectives

In material dynamics, we aim mainly to understand elastic deformation from the perspective of macroscopic mechanics, to understand the basic concepts of stress and strain and to deepen the understanding of the types of stress caused by various load types. Specifically, the contents stated in "Standard Level of Achievement" in the Rubric is the basic goal of this course.

Assigned Department Objectives

Learning and Educational Objectives of the “General Engineering” A-6 （核となる専門分野の既存技術を説明でき，社会から要求されている問題や実務上の問題を見出し設定することができる。）

Diploma policy 1 （To develop engineers who comprehensively acquire knowledge, focusing on mechanical engineering as the basis of manufacturing and production technology, and play a role in equipment design, technology development and other engineering-related fields.）

Teaching Method

Outline:

Strength of materials is one of the fundamental subjects of mechanical engineering, and is a necessary academic field in equipment design, etc. Students are not only required to understand material dynamics, but also, after graduation, they will be involved in equipment design, etc., using material mechanics as a tool. Students are not required to memorize for tests, but must understand the information properly so that they will acquire knowledge even after graduation.

Style:

Lecture

Notice:

Students should understand the fundamental hydrostatics of mass points and rigid bodies. Students are required to submit all reports. Except in cases of unavoidable circumstances, if there is even one report that has not been submitted, the unit will not be certified if you failed to comply with the submission deadlines.
