Planar slip-driven fatigue crack initiation and propagation in an equiatomic CrMnFeCoNi high-entropy alloy

, 2020
High-cycle fatigue crack initiation and propagation in an equiatomic CrMnFeCoNi high-entropy alloy were investigated using smooth specimens. The microstructural deformation characteristics, i.e., planar dislocation slip, significantly affected the ...

Mode I fatigue crack growth at notches considering crack closure

International Journal of Fatigue, 2010
Abstract Αn analytical elastic–plastic model is presented describing the fatigue life of arbitrary engineering components with elliptical notches under constant amplitude loading. A ΔJeff-based crack growth law is integrated from a starting crack size of micro-structural dimension up to the total fracture of the component.

Crack initiation angles and propagation paths in polyurethane foams under mixed modes I/II and I/III loading

Theoretical and applied fracture mechanics (Print), 2019
Rigid polyurethane (PUR) foams can be subjected to complex loading conditions when they are utilized as a structural material in engineering components. Under the influence of tensile or shear loads, the crack growth is one of the major failure modes for

Investigations of crack-dislocation interactions ahead of mode-III crack

Materials Science and Engineering: A, 2015
Abstract Transmission electron microscopy was employed to investigate the configuration of dislocations emitted by a sharp crack in Al 1100 and Ni base superalloy in part to understand the role of different stacking fault energies. A dislocation free zone and a plastic zone were observed ahead of the cracks in both cases with different dislocation ...
