The efficiency of the critical plane model of Smith, Watson, and Topper in estimating fatigue life for loaded notched shape memory alloy members undergoing thermal cycling is demonstrated. The field intensity approach is adopted, which characterizes fatigue damage over a critical notch root region rather than at a critical point.
