Direct Shear Test Apparatus For Testing Lab Description and Specifications for Lab Tenders
Direct Shear Test Apparatus.
The Direct Shear test apparatus consist of a square or circular box
divided into two halves. The specimen, contained in the box, is
subjected to a constant normal load while an increasing horizontal force
is applied to one of the sections of the shear box. This force causes a
shear failure along the juncture between the box sections of this. The
shear force and the normal load are measured directly. The rate of
strain is adjusted by the speed of the horizontal force applied. The
loading unit has V-strips on which the shear box housing rests. The load
yoke in these direct shear test apparatus helps counter balance the
loading system. The lead screw connected to the shear box housing helps
application of shear stress.
Direct Shear Test Apparatus comprises of
Direct Shear Box assembly for 60mm x 60mm x 25mm thick specimen,
Shear Box Housing
Specimen cutter
Loading Unit with a capacity of 8kg/cm2, set of weights to give normal stress of 3kg/cm2
Proving Ring duly calibrated by Nccbm (Govt) of 2.5kN (250kgf) capacity & 2 (Two) Dial Gauges 0.01mm x 25mm travel
The load yoke with direct and through level system for applying normal
load upto 8 kg/cm2 capacity, fixtures for proving ring, brackets for
holding consolidation and strain dial gauges are also provided in these
direct shear test apparatus.
