“…The research has employed two distinct mesh sizes, whereby the crack location's surrounding mesh-that is, the areas at the crack front and surrounding areas-is more sophisticated than the geometry of the other plates. In order to avoid convergence problems and obtain a more accurate SIF solution, a finer mesh is used at the fracture position (Jakeman et. al., 2022).…”

The present research focused to develop meta-model (MM) as a low-cost substitute for the Finite Element Method (FEM), to forecast the Stress Intensity Factor (SIF) of a semi-elliptic crack propagating. Multi-linear regression (MLR) based MM is developed for predicting the crack propagation. Three parameters—Root Mean Square Error (RMSE), Maximum Absolute Error (AAE), and Average Absolute Error—are examined to compare the MM's precision (AAE).
