This training supplies the tools needed to describe and apply the workflow for dynamic analysis in FLAC3D, demonstrating a comprehensive understanding of each step involved, including model setup, boundary conditions, input signal application, and damping, to effectively analyze dynamic behavior in geotechnical simulations.
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.
