1) Learn the appropriate application of fracture mechanic methodology for material strength assessment (Learning and educational goals [D and F]).
(2) Understand the statistical properties of material strength and learn about reliability engineering handling (Learning and education goal [D]).
(3) Understand the effects of various factors on material strength and acquire the ability to explain them to others (Learning and educational goal [H]).
Outline:
Strength and fracture of materials is a field that deals with the mechanical behavior of materials, such as deformation and destruction, which occur when external forces are applied to solid materials. It is related to other fields, including engineering materials like metal structure, the strength of materials and continuum mechanics, and reliability engineering. The aim of this course is to understand the effects of microscopic structures and various factors on various strength properties, and to learn about material selection and strength design methods for various machinery and structures.
Style:
Classes will be held in a lecture style.
Notice:
While it is preferable if students have completed Engineering Materials and Strength of Materials offered at Akashi Kosen Mechanical Engineering Department and other related subjects, classes will be taught from the basics as much as possible. This course's content will amount to 90 hours of study in total. These hours include the learning time guaranteed in classes and the standard self-study time required for pre-study / review, and completing assignment reports.
Students who miss 1/3 or more of classes will not be eligible for a passing grade
