About This Product
In the direct shear test a soil specimen is placed in a split shear box, loaded with a normal stress and sheared along the plane between the two halves, and the shear force is measured with a proving ring. Repeating the test at different normal stresses gives the strength parameters of the soil. A motorised unit with selectable strain rates allows slow rates to be used for drained tests on fine soils. Students use it in soil mechanics classes to plot shear stress against normal stress.
Frequently Asked Questions
Q1. What strain rates does the motorised Direct Shear offer?
It is electrically operated with 12 rates of strain: 1.25, 0.625, 0.25, 0.125, 0.05, 0.025, 0.01, 0.005, 0.002, 0.001, 0.004 and 0.0002 mm/min.
Q2. What specimen size and normal stress does it take?
The shear box takes a square specimen of 60 × 60 × 25 mm. The normal stress capacity is 8 kg/sq. cm, and the supplied weights give a normal stress of 3 kg/sq. cm.
