REVERSED STRESS & DESIGN:FINITE & INFINITE LIFE
Apr 9, 2021
Reversed stresses : Those stresses which have same magnitude of stresses but in opposite sense (i.e σ1 = -σ2).
Here, σm=0 & σv = σ1 or σ2
Fluctuating stresses : Those stresses which have different magnitude of stresses and also induces in a specific direction.
CASE 1: When the Component is to be designed for infinite life, the endurance limit becomes the criterion of failure.
CASE 2: When the component is to be designed for finite life particular, the particular S-N curve of the component becomes the criterion of failure.This case is used mainly for steels.
