Live in-person introductory training course. This four-day course provides guidance in the use of the Itasca codes PFC2D and PFC3D to simulate the mechanical behavior of granular and solid materials.
The contact theory developed by Johnson, Kendall and Roberts (Johnson et al., 1971) is known as the JKR model and is an extension of the well-known Hertz contact model.
The model accounts for attraction forces due to van-der-Waals effects. It can however be also used to model material where the adhesion is caused by capillary or liquid-bridge forces (Hærvig et al., 2017, Morrissey, 2013, Xia et al., 2019).
This implementation of a JKR model for PFC 6.0 has been tested in PFC3D Version 6.00.27, and not tested with PFC2D.
