Originální abstrakt

Crack closure slows down fatigue crack propagation and affects the crack front curvature. The purpose of this study was to determine the crack front curvature in the CT and MT specimens made of the EA4T steel, which were subjected to cyclic loading. The methodology of constant plastic component of CTOD along the crack front was used in finite element modeling. Results confirm negligible effect of the in-plane constraint on fatigue crack propagation, taking into account PICC.
