Cyclic strength of sand under a nonstandard elliptical rotation stress path induced by wave loading被引量：2
《Journal of Hydrodynamics》2017年第1期89-95,共7页王忠涛 刘鹏 Dongsheng Jeng 杨庆 
Project supported by the Natural Science Foundation of China(Grant Nos.51639002,51209033);the Specialized Re-search Fund for the Doctoral Program of Higher Education(Grant No.20120041130002)
The principal stress rotation is one of the most important features of the stress state in a seabed subjected to wave loading. Most prior investigations focused their attention on the cyclic behaviour of soil deposits...
