Bonded Particles

LIGGGHTS® features high-performance, open source, customizable DEM simulations.
It also incorporates a model for bonded particles. Bonds can take tension, compression, tangential forces, bending torque and torsion torque

This is a feature which is not part of the public release, and is made availaible to customers of DCS via a commerical support version for industrial users ("Premium version")

The following example shows a beam with 2 fixed bearings and a cylinder with 6 degrees of freedom under gravity.
Plastic deformation results from cylinder weight - after settling, bearings are "wiggled" sinusoidal
