Improving an input of material model in the D-Dempack package programme in the Kratos application of granular non-cohesive materials

The main objective of this document is to present an idea of calibration tests used to improve input material model in the DEM simulations in the D-DEMPack package programme in the Kratos application, which is developed in CIMNE. Presented method lets increase the precision and validity of discrete element modeling work.
The calibration tests presented in this protocol may be used for granular non-cohesive materials (for loose, dry granular material). They concern only the sphere shape of particles. The tests were conducted on couple different sizes of particles, in this work are presented results for average diameter of grains equal to 5cm (normal distribution with deviation equal to 0’05).
The results of research may provide a basis for proper computing project data for preparing material model for loose, dry granular material. Tested by the autor methods have been developed based on an article
