Abstract The main objective of this work is to model wear a disc which was subjected dry contact with ball in unidirectional sliding. Tribological tests sliding pairs were carried out using tribological tester T-11 ball-on configuration. Stationary balls made 100Cr6 steel hardness 62 ± 2 HRC co-acted rotating discs 42CrMo4 40 2HRC. Discs machined by lapping, grinding, milling, and vapour blasti...

To study the failure modes, bearing capacity, ductility, and sleeve strain of grouted lapping connectors, 36 specimens were tested under uniaxial tensile load. The test results show that sleeves are longitudinal tension at beginning, which changes to compression in late stage loading, changing load increases gradually with lap length. force transmission path mechanical mechanism connectors anal...
