Numerical modelling of honeycomb core crush behaviour ...
2008-6-1 · The homogenised FE model may be used for large structures, but gives poor agreement when failure is due to core crushing. The SAC model is shown to be most appropriate for use in structural simulations with extensive compression core crushing failures, since the discrete particles are able to model the material compaction during local crushing.

2022-1-28 · I've worked on a lot of projects where we used the cut whole-diameter PQ core for the Bond low-energy impact crushing test. One instance where the core was crushed instead of loaded into the test resulted in quite different values (lower results than whole-diameter) which we interpreted as the crushing pre-stressing the rock creating fractures.
