I now include this paper in my course on fracture mechanics.
Dear Colleague,
Dr. Saeed Zare Chavoshi and I have co-authored three review articles, concerning nanoindentation and nanoscratching at finite temperatures from the computational and experimental perspectives:

The fundamental problem of friction in the presence of macroscopic adhesion, as in soft bodies, is receiving interest from many experimentalists. Since the first fracture mechanics 'purely brittle' model of Savkoor and Briggs, models have been proposed where the mixed mode toughness is interpreted with phenomenological fitting coefficients introducing weaker coupling between modes than expected by the "purely brittle" model.
The High Luminosity (HiLumi) upgrade of the Large Hadron Collider (LHC) relies, amongst other additional upgrades, on superconducting 11 T dipole magnets for increasing the luminosity of the beam to enlarge the data sample for physics experiments. The new dipole magnets are manufactured from Nb3Sn superconducting elements that become very brittle after a very specific and necessary heat treatment during the manufacturing stage.
