Abstract

The ability to model rigid body interaction with highly deformable solids is a very useful tool in geoengineering, including the modelling of drag anchors on seabeds and seabed ploughing [7, 1]. However, these simulations entail several numerical challenges, such as modelling frictional contact, and incorporating inertia forces for analyses whose simulated time is considerable. Here the implicit Generalised Interpolation Material Point Method (GIMPM) is adopted to model the highly deformable solid, whilst a rigid body is used to model the significantly stiffer engineering object, such as an anchor. The whole system is integrated in time with the Newmark method with interaction between the two bodies occurring through a normal penalty contact and a penalty enforced Coulomb stick-slip friction law.
