Algorithmic formulation of clay and sand pipe–soil interaction models for on-bottom stability analysis
Longva, Vegard; Ji, Guomin; Sævik, Svein; Ye, Naiquan; Gjøsteen, Janne Kristin Økland; Giertsen, Egil; Wang, Yanbin (Peer reviewed; Journal article, 2021)This paper presents a new algorithmic formulation of the clay and sand pipe–soil interaction models recommended by the DNV-RP-F109 code for dynamic on-bottom stability analysis of submarine pipelines. The pipe–soil force ... -
