Class Objectives
/Class Outline In mechanics of materials, structural components are typically modeled as bars or beams, and stresses, deformations, and deflections are evaluated based on such simplified representations. In this course on elasticity, these concepts are further developed to address mechanical components and structural elements with more complex geometries. Students will study theoretical methods for analyzing the distribution of stress and strain within elastic bodies.
The course aims to develop the ability to understand the governing equations of elastic bodies and to express stress and strain components under arbitrary coordinate systems. Students will also acquire analytical methods for solving elasticity problems with boundary conditions and develop the fundamental competence required to address stress concentration problems in mechanical and structural design.

Suggestions on
Preparation and
Review Students are expected to thoroughly prepare for and review the content of Strength of Materials. In addition, by making effective use of the notes taken during class and working on the assigned practice exercises, students should ensure a solid understanding of the material.

Requirements Full attendance is expected. Late arrival and early departure will be treated as absences. In addition, the use of smartphones, PCs, or other devices for purposes unrelated to the class during lectures is prohibited.

Grading Method The final grade is based on a total score of 100 points, consisting of exercises (approximately 30%), a midterm test (approximately 30%), and a final examination (approximately 40%). A score of 60 points or higher is required to pass.
