Another shear test was developed and used by Herrmann. Figure 46 is a schematic representation. The apparatus was conceived such that briquettes produced under vacuum in an experimental piston press could be tested within the vacuum chamber, where (1) is the lower (press) piston and (8) is the upper piston. The press die (4) is fitted with a shear slide (9) under a cover plate. To neutralize the radial stresses caused by and depending on compaction pressure, the briquette is first ejected from the die (4) and then refitted with an insertion force of 300 N. Then, the entire shear cell is removed from the press table by...

In present geological conditions the increase in differential pressures is most likely to enlarge the range of water-saturated mudstone that will further alleviate its strength and will increase the potential for shear-sliding by lubricating the fracture surfaces.

The fracture behaviour and mechanical properties of the composites are generally influenced by the interfacial structure or the fibre/matrix interactions. The nonlinear behaviour in the L-D curve and the pull-out of the fibre from the matrix without plastic deformation have demonstrated experimentally that the weak bonding between the fibres and by the van der Waals force allows the shear sliding deformation at tiie interface. The weak interaction between the...
