Simplified JKR model for evaluating the cohesion property of powders in DEM simulations

Discrete element method (DEM) is a numerical technique that enables investigating flow of powders. A powerful software which applies this method is LIGGGHTS. LIGGGHTS provides a series of commands in C++ for calculating the contact forces among particles. One of these contact forces developed by LIGGGHTS is the simplified Johnson-Kendall-Roberts (SJKR) model. This model is suitable for the calculation of cohesive forces. This study discusses the SJKR contact model and review its application in different cases.
