Insight of molecular simulation to better assess deformation and failure of clay-rich rocks in compression and extension

open access: yesInternational Journal of Rock Mechanics and Minings Sciences, 2021
Clay minerals constituent an essential component of clayey rocks. Macroscopic mechanical behaviors of those rocks can be significantly driven by local deformation and failure processes of clay minerals.

Effect of water saturation on Cerchar abrasivity index (CAI) of clay-rich rocks at different scratch lengths

open access: yesWear
Predicting the cutter consumption rate of mechanical excavators using the Cerchar abrasivity index (CAI) results is possible. However, changing operational parameters in the field may cause differences between the estimated cutter consumption rate based on CAI test results and the real cutter consumption rate observed in the field. One of the essential
