Peridynamic modelling of clay erosion

Experimental observations of the erosion clays indicate a high degree coupling between hydro-chemical processes in clay–water system and mechanics erosion. In contrast with volume experimental work significance swelling clay many geotechnical engineering problems, limited advances have been made predictive modelling this phenomenon. The critical step, missing existing models, is particles’ detachment from moving boundary expanding – discontinuous process. This paper presents, for first time, non-local formulation erosion, which brings together swelling, particle detached transport, into single tool. criterion, an essential element integrated model, tested against series benchmarks to show excellent agreement calculated results. model subsequently validated by comparison data behaviour compacted bentonite under several eroding environments. results: (a) clearly capacity capture concurrently free clay, particles transport environment; (b) support strongly applicability account conditions (composition velocity) environment. proposed multi-physics formulation, successfully effects on provides robust framework incorporating wide set additional couplings.
