A series of cyclic constant-volume direct simple shear (CDSS) loading tests was performed on Malaysia offshore clay to study its undrained degradation. The testing program consists of stress-controlled tests with cyclic shear ratio ranging from 0.34 to 0.83 at different overconsolidation ratios (OCRs). For a given cyclic stress ratio in stress-controlled tests, the accumulated cyclic strain and pore water pressure increase with elevated number of cycles. In heavily overconsolidated clay specimens, the negative cyclic pore water pressure is generated followed by positive cyclic pore water pressure as cyclic tests progress. The post-cyclic strength of offshore clay specimens is reduced by undrained cyclic stress-controlled loading. � 2017 Institute of Rock and Soil Mechanics, Chinese Academy of Sciences Final 2023-05-29T06:39:00Z 2023-05-29T06:39:00Z 2017 Article 10.1016/j.jrmge.2016.06.013 2-s2.0-85015803251 https://www.scopus.com/inward/record.uri?eid=2-s2.0-85015803251&doi=10.1016%2fj.jrmge.2016.06.013&partnerID=40&md5=c7541da00a05126c7185f8a716d5d922 https://irepository.uniten.edu.my/handle/123456789/23274 9 2 376 381 All Open Access, Gold Chinese Academy of Sciences Scopus |
