Load history effects on fatigue crack propagation: Its effect on the R-curve for threshold
The study deals with the effect of load history during threshold and fatigue crack propagation measurements in the near threshold regime. The compression pre cracking and the stepwise increasing load amplitude test was applied. The effects of pre-cracking as well as the effect of compression and t...

| description | The study deals with the effect of load history during threshold and fatigue crack propagation
measurements in the near threshold regime. The compression pre cracking and the stepwise increasing load
amplitude test was applied. The effects of pre-cracking as well as the effect of compression and tension
overloads after the pre-cracking on the long crack threshold and on the R-curve of the threshold of stress
intensity range are analysed. |
