EDEM Technical Webinar Series

These webinars were presented live in May and June, 2020.

Watch the recordings of our special technical webinar series where our EDEM experts cover a range of topics including calibration, particle shape, physics models, advanced post-processing as well as how to model complex fine materials such as powders and soils.

  • Introduction to EDEM Calibration Method and Technology

Material calibration is essential to link real world material behaviors with the virtual material to give confidence to engineers that their simulations are representative. This webinar explains the importance of calibration and describes a material model calibration method that can be used by engineers in different industry areas. Additional support tools available to EDEM users are also presented, including the GEMM database, starter packs and EDEM Cal.

  • Meso-scopic Modelling of Powders and Soils in EDEM

Modelling fine particulate solids such as powders and soils with the classical micro-mechanical formulation of DEM is challenging due to the large number of particles involved. In this webinar, we introduce the meso-scopic modelling approach which can capture the complex behavior of fine particulate solids, while utilizing a numerical particle size of an intermediate scale between the physical particle scale and the scale of the system of interest. A meso-scopic contact model is introduced and examples of experimentally validated results from bench scale physical tests are given along with examples of EDEM models for large scale systems.

  • Design for Dirt! Optimizing Equipment & Vehicle design by coupling EDEM with Multi-body Dynamics

When designing heavy and off-road equipment, being able to accurately predict the loads and forces acting on equipment and understanding how vehicles interact on different terrains is key to optimizing performance. This webinar explains how this can be achieved by coupling EDEM with Multi-body dynamics tools such as Altair MotionSolve, and shows how this solution enables engineers to perform extensive “what-if” design analysis early in the design cycle and to reduce costs associated with physical prototyping.

  • Experimentally Validated DEM Model of a Triaxial Test on Railway Ballast Utilizing the Multi-sphere Approach

This webinar presents the EDEM modelling of a triaxial test on railway ballast, focusing on methods for achieving excellent numerical predictions of the experimentally measured stress-strain response with the multi-sphere approach. The bonded-particle method for modelling the membrane boundary condition of the physical test is also discussed and its effect on the imposed stress-state in the model is evaluated using coarse-grained stress calculations generated with the EDEMpy library of post-processing functions.
