Abstract
Highlights
-
A coupled plasticity-damage MPM framework considering particle-to-surface contact is constructed.
-
The effectiveness of the constructed MPM framework for rock spalling/failure simulation is confirmed.
-
Spalling is reproduced by the sequential appearance of multiple cracks starting at the opening surface.
-
The filling of nearby open flaws could exacerbate the spalling and cause even massive collapse.
