Review of modeling tool‒rock frictional contact with a blunt PDC cutter
Journal of Intelligent ConstructionThe mechanisms of tool‒rock frictional contact are reviewed, with a focus on recent advances in numerical modeling. An idealized problem is defined for tool‒rock frictional contact with a rigid blunt tool sliding on the surface of a half-space.

Stress intensity factors in a cracked infinite elastic wedge loaded by a rigid punch [PDF]
A plane elastic wedge-shaped solid was split through the application of a rigid punch. It was assumed that the coefficient of friction on the the contact area was constant, and the problem had a plane of symmetry with respect to loading and geometry ...
