## What is/are Stress Induced Phase?

Stress Induced Phase - Beyond this range materials are either insufficiently stabilized which results in poor strength and high tendency to LTD, or overstabilized and no longer susceptible to stress induced phase transformation and therefore too brittle.^{[1]}Due to the thermomechanical nature of the phase transformation, the area of functional fatigue can be further subdivided into pseudoelastic fatigue, which is fatigue due to stress induced phase transformation, or actuation fatigue which is fatigue due to repeated thermally induced phase transformation.
