Course description and aims
Reliability and durability are highly required in use of metallic materials for structural applications such as automobiles, airplanes and thermal power plants etc. This course first gives an introduction of fracture of metallic materials in real applications and fracture manners. The introduction is followed by basic lectures on fracture mechanics, fatigue and creep deformation which are important phenomena in terms of reliability and durability of metallic materials. In the lectures on fatigue you will study S-N curves, and nucleation and propagation of cracks. In the lectures on creep deformation students will learn high temperature deformation mechanisms and design principle of the materials for improved durability.
Student learning outcomes
Students will be able to:
1) Understand the importance of reliability and durability of metallic materials for structural applications.
2) Understand the basics of fracture toughness and its importance in terms of reliability of metallic materials.
3) Understand the basics of fatigue and creep deformation and its importance in terms of the durability of metallic materials.
4) Understand how to design, select and test metallic materials to be used for structural applications.
