Original abstract
Many studies dealing with fatigue crack tip plastic zones assume only two-dimensional plane strain or plane stress condition. This has non-negligible impact on a shape and a size of plastic zones. The purpose of this study was to emphasize the difference between plastic zones obtained from 2D simulations and 3D simulations in CT specimen made of the EA4T steel. The results confirmed the importance of 3D simulations with real crack front curvature.
