How to calculate the coefficient of stricture?


How to calculate the coefficient of stricture?
- R0: elastic limit
- Rp0.2: conventional yield strength.
- E: Young’s modulus.
- Rm: tensile strength.
- AR(%): plastic elongation after rupture.
- AR(%)=100 (lrup – l0)/l0.
- Z: necking coefficient.
- Z=100(S0 – Srup)/S0.
What is Adaptive Stress?
Acute and short-term stress is called “good stress” in that it is mobilizing. “In this case, the hormones secreted allow a dynamic reaction which aims to overcome the apprehended situation, if we manage to cope with the situation we speak of adaptive stress or good stress”, according to Doctor Alexandre Hubert.
