Grain-scale DEM study of open-ended pipe pile penetration in granular soils [PDF]

EPJ Web of Conferences, 2021
Open-Ended Pipe Piles (OEPP) are particularly popular in offshore engineering. An important feature of the installation of these piles is the rate with which soil enters the pile from the bottom, and its interaction with the internal pile shaft.
