Numerical simulation of rock cutting process induced by a pick cutter considering dynamic properties of rock at intermediate strain rate

Rock excavation is a dynamic process where rock is dynamically loaded by mechanical cutting tools. Previous researches have shown that rock strength in dynamic loading is greater than that in static loading. However, existing prediction models for mechanical excavation of rock do not take into account the dynamic features of the rock. This issue has the potential to deliver misleading outcomes when estimating cutting performance and assigning an...
