Effects of cyclic loading on lateral bearing capacity of single pile in silty seabed
Yantu gongcheng xuebaoUnder larger wave loading, the bearing capacity of marine single pile foundation will be reduced, even instability occurs. A series of undrained shear triaxial tests on the remolded marine silt in Hangzhou Bay are carried out by means of the GDS triaxial

Effect Of Single Overload Ratio And Stress Ratio On Fatigue Crack Growth
, 2013 In this investigation variation of cyclic loading effect on fatigue crack growth is the studied. This study is performed on 2024 T351 and 7050-T74 aluminum alloys, used in aeronautical structures. The propagation model used in this study is NASGRO model. In constant amplitude loading (CA), effect of stress ratio has been investigated.
