Discrete element modeling study on CPT penetration of calcareous sand considering dual porosity structure

This paper introduces a discrete element numerical simulation method for calcareous sand particles that incorporates dual porosity structures. The method focuses on three key characteristics of calcareous sand in comparison to quartz sand: abundant dual porosity structure, pronounced particle aspect...
