Simulation of rock-breaking process of polycrystalline

ABSTRACT. Stick-slip vibration is commonplace in the drilling of polycrystalline diamond compact (PDC) bit, which leads to early bit failure, low drilling efficiency and high drilling cost. Inspired by the application of torsional impactor, this paper establishes a nonlinear dynamic 3D numerical simulation model, in which the Drucker-Prager criterion is taken as the yield criterion of the rock.

What is Erosion? Process and Examples of Erosion

By Water. Water, when flowing through downhill, can easily take away soil along with other rock particles. The natural change of temperature forces the rock pieces to get out of the earth’s surface. Besides, the acidic properties found in the rainwater also break up rocks that contain calcium carbonate, which is just the process that we call weathering.

How to Look at a Rock Like a Geologist

Jan 13, 2020 Rocks get dirty and decay: wind and water make every kind of rock slowly break down, a process called weathering. You want to observe both fresh and weathered surfaces, but the fresh surface is most important. Find fresh rocks in beaches, roadcuts, quarries, and streambeds. Otherwise, break open a stone. (Don't do this in a public park.)
