Experimental studies of scale effects on shear strength, and deformation of rock joints [PDF]

open access: yes, 1980
The effect of scale on shear strength is studied by performing direct shear tests on different sized samples of large joints. A rubber moulding system is used to obtain impressions of the roughness from a variety of natural joint surfaces.

Mechanical strength of silica fiber splices after exposure to extreme temperatures [PDF]

open access: yes, 2012
By using a combination of type-I and regenerated gratings, the mechanical strength of optical fiber splices after exposure to temperatures over 1300 C was characterized. Splice strength was found to decrease with temperature with a secondorder polynomial

Unwinding of a cholesteric liquid crystal and bidirectional surface anchoring [PDF]

open access: yes, 2013
We examine the influence of bidirectional anchoring on the unwinding of a planar cholesteric liquid crystal induced by the application of a magnetic field. We consider a liquid crystal layer confined between two plates with the helical axis perpendicular
