Chapter 7. Mechanical Properties of Metals II Fracture and ...
physics.uwo.caChapter 7 1 Chapter 7. Mechanical Properties of Metals II Fracture and Failure 1. Fracture - ductile fracture - brittle fracture - ductile to brittle transition T 2. Fatigue: - fatigue failure - fatigue crack growth rate 3. Creep (time-dependent deformation) - creep rate - Larsen-Miller parameter How to improve mechanical characteristics?
Chapter 4. Lagrangian Dynamics
physics.uwo.caHamilton’s Principle, from which the equations of motion will be derived. These equations are called Lagrange’s equations. Although the method based on Hamilton’s Principle does not constitute in itself a new physical theory, it is probably justified to say that it is more fundamental that Newton’s equations.
