Adaptive Finite Element Prediction of Fatigue Life and Crack Path in 2D Structural Components

open access: yesMetals, 2020
The existence of a hole near a growing fatigue crack can cause the crack trajectory to deviate. Unless the hole is too close to the crack, the crack is arrested at the edge of the hole and does not progress further.
