Witryna21 lis 2024 · For this purpose, three cohesion contact models were tested: linear cohesion in EDEM, and simplified Johnson-Kendall-Roberts (SJKR) and modified SJKR (SJKR2) in LIGGGHTS. The influence of the particle size distribution (PSD) on the results was also investigated. Witryna24 lis 2024 · The Hertz–Mindlin with JKR (Johnson–Kendall–Roberts) contact model is a cohesive contact model that incorporates the influence of van der Waals forces in the contact area into the calculation. The JKR model uses the same calculation method of the Hertz–Mindlin model to calculate tangential elastic force, normal dissipative …
WitrynaThe Hertz-Mindlin with JKR Version 2 (JKR V2) model implemented in EDEM captures the behavior of multiple materials and uses a more accurate implementation of the JKR theory. It calculates the additional work required to break the contact (adhesion) after physical detachment of particles, thus making it applicable to contacts involving very ...
