| | Summary: |
| | During our research we have investigated the properties of concrete with
discrete element method (DEM) to have a better understanding on the processes inside
the material. With DEM it is possible to model porous materials (e.g. concrete) on
macro level, which requires the setup of different material parameters.
One of these parameters is the standard deviation of the contact normal strength. This
parameter is usually set to 10% based on the recommendation of the software developer
company. This parameter value was not exactly developed for concretes, but for other
stone-like materials.
In this study the effect of this parameter is investigated from 0% to 100% for concretes
with compressive strength varying between C12/16 and C40/50. |
