Modelling fatigue crack growth in shape memory alloys
Dear iMechanicians, I hope that you find the below work interesting. We have developed a phase field-based computational framework for predicting fatigue crack nucleation and growth in Shape Memory Alloys. The model captures the role of transformation stresses, stress-strain hysteresis, and temperature. And this is demonstrated by computing Δε − N curves, quantifying Paris law parameters, and predicting fatigue crack growth rates in several geometries, including the fatigue failure of a 3D lattice structure.
