Grahic Jump Location
(a) Typical attachment load history, (b) example load history
Grahic Jump Location
Schematic of two elastic bodies in partial slip contact. a1 and a2 denote the ends of the contact zone and b1 and b2 denote the end of the stick zones.
Grahic Jump Location
The evolution of the contact and stick zones and the “slip lock” phenomenon that occurs during the incremental indentation of an elastic half-space by a rigid surface
Grahic Jump Location
Stick zone size as a function of the coefficient of friction. The values of b/a obtained by solving the coupled singular integral equations incrementally are in good agreement to those obtained by Spence 7 using a self-similar analysis.

Shear traction results when a rigid cylinder is brought into contact with a Ti-6Al-4V half-space for two different load histories (P=1.75 MN/m,Q=0.35 MN/m)
Grahic Jump Location
Shear traction results when a cylinder made from Inco718 alloy is brought into contact with a Ti-6Al-4V half-space for two different load histories (P=1.75 MN/m,Q=0.53 MN/m)
Grahic Jump Location
Mission points 19, and 20 with Ti-6Al-4V cylinder contacting Ti-6Al-4V half-space

Grahic Jump Location
Change in shear traction due to a 2% increase in normal load and keeping the shear load and moment constant. The initial distribution of the shear traction is shown in Fig. 8(c). Note that a and b denote the size of the contact zone and the size of the stick zone, respectively.
