Relaxation in Traction: Deformation and Hardening

This lecture covers the concept of relaxation in traction, where the force returns to zero, leading to permanent deformation. It discusses the real tensile curve, relaxation rate, and the method to calculate strain rate in relaxation. The lecture also explores the anticipation of elastic rebound, calculation of strain, and the transfer equation for work-hardened parts. It delves into the hardening process, work hardening law, and the behavior of hardened parts. Additionally, it explains the relationship between strain rate and hardening, the ultimate tensile stress, and the implications of the transfer equation.
