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.
A new plasticity bond damage model for highly porous, soft rocks is proposed and implemented as a contact model in the discrete element method DEM. The Particle upscaling law for strength, softening, and far-field interaction parameters are presented and validated in Zheng & Ciantia (2025) enabling computational efficiency. Also, a strength correction equation is developed in Zheng & Ciantia (2025) to consider sample size effect of rocks. Finally, for boundary value problems like pile installation, the computational improvement of the model led pile penetration simulations in porous, soft rocks for the first time conducted in Zheng & Ciantia (2025).
