DEM-based algorithm for simulation of rocking developed

Posted on by

The first DEM-based algorithm available to simulate rocking of a single rectangular block on a base is developed in Matlab. The first version of the code includes only normal contact between the bodies, while tangential contact will be added later.

The normal contact is modeled as:

  • Undamped linear spring model,
  • Damped linear spring model ,
  • Undamped Hertzian model,
  • Damped Hertzian model.
