In this study, the growth behaviour of short fatigue cracks in En7A steel with a high content of elongated MnS inclusions has been investigated by generating and evaluating short crack growth data for the six principal specimen orientations. The anomalous initiation and growth behaviour of short cracks was also compared with that of long crack data for the same material and loading conditions determined before. This comparison revealed the sub-threshold initiation and faster growth rate of short cracks compared with long cracks under the same stress intensity factor range. In order to simulate this discrepancy between short and long cracks, a crack closure model for long crack data was used.

Inclusion induced anisotropy of short fatigue crack growth in steel
Kaynak, Cevdet; Baker, TJ (Informa UK Limited, 1996-07-01)
In this study, the growth behaviour of short fatigue cracks in En7A steel with a high content of elongated MnS inclusions was investigated by generating and evaluating the short crack data under different loading conditions for the six principal specimen orientations. Short cracks showed a strong anisotropic behaviour in which they grew much faster in the transverse and short transverse orientations than in the longitudinal orientations in all fatigue processes. This was due to the relatively high content o...
Initiation and early growth of short fatigue cracks at inclusions
Kaynak, Cevdet; Baker, TJ (Informa UK Limited, 1996-05-01)
In this study, the initiation and early growth behaviour of short fatigue cracks in En7A steel with a high content of elongated MnS inclusions was investigated by generating and evaluating data on the growth of short fatigue cracks under various stress levels and stress ratios for the six principal specimen orientations. Short cracks usually initiated at the debonded interfaces between the matrix and the inclusions. If there was no debonding, cracking sometimes occurred in the inclusions. In the early stage...
Effects of short cracks on fatigue life calculations
Kaynak, Cevdet; Baker, T.J. (1996-01-01)
In this study, the potential impact of the short crack problem in En7A steel with a high content of elongated MnS inclusions has been observed. Experimental short crack data were compared first with the predicted S-N curves determined using long crack growth parameters and second with the calculated lives using only long crack data and using both short crack and long crack data. All these life predictions revealed that long crack data alone cannot be used in fatigue lifetime analyses that treat short crack ...
Short fatigue crack initiation at inclusions

A comparative study of force-deformation relationship of FRP-confined concrete columns
Erdil, Barış; Akyüz, Uğurhan; Yaman, İsmail Özgür; Irfanoglu, A. (null; 2011-10-26)
In this study, the FRP-confined concrete models for prismatic members given in the ACI440.2R-08 and Turkish Earthquake Code (TEC2007) are compared with the experimental data taken from the literature. It is found that TEC2007 assumes only hardening behavior for concrete strengthened with FRP. Although ACI440.2R-08 assumes a hardening and softening behavior depending on the confinement-effectiveness, the limit separating the hardening and softening must be improved to predict the behavior well. The assumptio...
