Right: Deformed configuration of the fluid phase
During uplift of the pile, only the fluid phase follows the pile, while the solid phase separates from the pile tip
How to model the interface between a structure and a saturated porous medium?
In our latest paper published in ๐๐ฐ๐ฎ๐ฑ๐ถ๐ต๐ฆ๐ณ ๐๐ฆ๐ต๐ฉ๐ฐ๐ฅ๐ด ๐ช๐ฏ ๐๐ฑ๐ฑ๐ญ๐ช๐ฆ๐ฅ ๐๐ฆ๐ค๐ฉ๐ข๐ฏ๐ช๐ค๐ด ๐ข๐ฏ๐ฅ ๐๐ฏ๐จ๐ช๐ฏ๐ฆ๐ฆ๐ณ๐ช๐ฏ๐จ (CMAME) we present a mortar contact discretization scheme enforcing contact constraints separately for the pore fluid and the solid.
Back-calculation of vibratory pile driving tests shows that the proposed scheme increases both numerical stability as well as predictive capabilities of the simulation compared to contact methods not distinguishing between contact constraints for the solid phase and the fluid phase.
