The relationship between recovery stress and temperature of shape memory alloys in static heating and dynamic heating condition has been researched. In former condition

an iterative method for constitutive model

which could predict recovery stress effectively

was raised. The limitation of traditional model in later condition has been expressed as well. Therefore

an efficient method called mean rate interpolation has been proposed. With this method

the result of SMA’s recovery stress in dynamic heating condition can be calculated accurately

whose relative error is less than 10%.
