Research abstract
Recent research has shown that legacy stress intensity solutions produce inaccurate estimates of fatigue crack growth life which can lead to inaccurate inspection intervals. The proposed program would develop a combination of machine learning and nonlinear finite element analysis (FEA) to remedy the discovered inaccuracies and automate the development of updated stress intensity solutions.
