Fig. 3: Comparison of error in predicted crack surface area.

From: An interleaved physics-based deep-learning framework as a new cycle jumping approach for microstructurally small fatigue crack growth simulations

Fig. 3

Projected absolute error in total crack surface area relative to a corresponding physics-based simulation (ground truth), plotted as a function of nominal crack size. Results are shown for deep-learning-only framework and the interleaved PBDL framework with two different cumulative uncertainty thresholds, T1 and T2. The inset shows actual data points from a specific microstructural instantiation, which are used to extrapolate to a final crack size that would be detectable by ultrasonic testing.
