a) Mean stress, om = MPa
b) Stress amplitude, a = MPa
c) Stress ratio, R =
Answers: 2
- Mean stress, measured in megapascals.
- Minimum stress, measured in megapascals.
- Maximum stress, measured in megapascals.
and 
, the mean stress is:
is the stress amplitude, measured in megapascals.
) is the ratio of the stress amplitude to mean stress. That is:
