Material Database for DEM with thousands of Material Models

Discrete Element Method (DEM) specialist, DEM Solutions, is introducing a ‘world first’ with the launch of the GEMM) (generic EDEM material model database. This database addresses one of the key challenges of DEM simulation: getting suitable material inputs for accurate representation of bulk materials.

As real materials come in a variety of shapes and sizes, their flow characteristics can vary greatly.

The new database contains thousands of material models representing a wide range of materials such as rocks, soils and ores and is particularly suited for engineers in the mining, construction and agriculture industries who design heavy equipment handling such materials. As real materials come in a variety of shapes and sizes, their flow characteristics can vary greatly and engineers are constantly challenged on how to ensure simulations show real material behaviour. In order to make a material model, engineers need to provide a wide range of inputs, all of which impact on the material behaviour. The traditional approach consists of trial and error and often a great deal of guesswork which can be very time consuming until engineers arrive at the set of parameters which best represents their material.

By applying their extensive experience, the team at DEM Solutions has been able to populate the database with thousands of material models ready to use in their simulation software to represent a wide range of material behaviours. This ensures that EDEM users will no longer have to rely solely on guesswork, but will be able to access a material model that reflects the material behaviour that they are looking for. The system asks users to input a set of basic information about the material to be represented which then triggers a search through the extensive database and returns a recommended material model based on their application and material requirements. The database will be freely available to EDEM users with current software licences who will be able to use the material models directly in EDEM.
