...–strain response. The results also show the relevance of time-dependent effects. Under monotonic strain-controlled conditions, such effects induce a strong strain rate dependence of the peak strength. Under cyclic stress-controlled loading, the fatigue life is shown to be influenced by the loading period...

...Zhechen Hou; Barry M. Lehane; Phillip G. Watson The time dependence of pile shaft friction in clay is well known. However, our understanding of the mechanisms causing capacity increase after consolidation is limited and there is considerable uncertainty on the magnitude of long-term gains...
