Spudcans are conical footings used as foundations for offshore platforms. Installation in soft marine soil forces them deeply into the seabed, inducing gross motion and severe plastic deformation in the soil.
A pure Lagrangianbased finite element approach for modeling spudcan installation and extraction can be very difficult. Because the mesh moves with the material, element distortion typically accompanies severe deformation and convergence difficulties follow.
In an Eulerianbased method, material flows through a fixed mesh; it is therefore more amenable to the simulation of large material motion and extreme deformation. Abaqus/Explicit offers the coupled EulerianLagrangian technique, in which chosen portions of the model can be modeled as Eulerian or Lagrangian, while automatically maintaining contact between the distinct regions.
In this Technology Brief the coupled EulerianLagrangian analysis method is used to model the installation, extraction, and insitu loading behavior of spudcans.
Clipping is a handy way to collect and organize the most important slides from a presentation. You can keep your great finds in clipboards organized around topics.
