Abstract

An implicit MPM program has been developed to model the 3D installation of screw piles for offshore wind turbine foundations as part of a UK EPSRC-funded project. The program is to be used to study the torque and vertical force requirements during installation of screw piles for different geometries and soil conditions, and has required the development of innovative numerical techniques which may be of interest for other geotechnical problems. In this paper, we introduce some of the features developed, including an efficient walking-in-triangulation algorithm for searching material points and an 푭̅-patch method for avoiding volumetric locking.
