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.

Simulation of delamination-migration and core crushing

2020-8-6 · A detailed three-dimensional nite element model of a test specimen was created to develop a simulation method for honeycomb core crushing. This model was modi ed into three variants each using a di erent approach for simulating delamination-migration in the facesheet. The migration simula-

2015-12-1 · The first model considered corresponds to the test where no Teflon® insert was present in the loaded facesheet and any appreciable damage in the specimen consisted entirely of core crushing. Damage in the core during the crushing process consists of both structural and material failure in the form of buckling and plastic deformation, respectively.

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.
