Numerical Investigation of Drilling Process for Complex Polar Ice Interlayers: An F-DEM Study
Subglacial drilling through polar ice–rock transitional zones is frequently hindered by severe load fluctuations and instability induced by strong formation heterogeneity. This study investigates the coupled drilling mechanics across pure ice, an ice–rock mixture, and bedrock using a fracture-mechanics-based finite–dis...
