This course aims to teach students of non-mechanical engineering course basics of strength of materials to learn how to consider problems from the mechanical perspective. Topics include mechanical properties, stress and complicated stress, bending, twisting, strain energy, impact loading, buckling, stress concentration, plastic deformation and creep, fatigue and fracture, and nondestructive testing methods.
By the end of this course, students will:
1. be able to explain the mechanical properties of materials
2. be able to calculate stress, strain, and deformation by external forces and moments
3. be able to explain mechanical behavior of materials which are necessary to design, produce, and maintain machines
Corresponding educational goals are:
(1) Specialist skills: Fundamental specialist skills
(4) Applied skills (inquisitive thinking and/or problem-finding skills) Organization and analysis
(7) Skills acquiring a wide range of expertise, and expanding it into more advanced and other specialized areas
stress, strain, moment
|Intercultural skills||Communication skills||Specialist skills||Critical thinking skills||Practical and/or problem-solving skills|
Towards the end of class, students are given exercise problems related to what is taught on that day to solve.
