Smaller the value of c (fatigue ductility exponent) ____________ will be the life of component.

Smaller the value of c (fatigue ductility exponent) ____________ will be the life of component. Correct Answer longer

The relationship between the fatigue ductility exponent and cycles is given by: -> Δεp/2=ε’f (2N)c So, if smaller the value of c, smaller will be the strain amplitude and longer will be the life of the component.
