Linear model

Using the linear model, the cyclic stress-strain curve is the same as the monotonic curve in the linear region. This rough approximation can be used for cyclic stress-strain conversion when the stress level is low, and the relation can be written as:

	Ramberg-Osgood model
Power hardening model
Linear model
Monotonic curve
Cyclic yield
Monotonic yield
