Soilmatic Direct / Residual Shear
The innovative Soilmatic philosophy provides a fully computerized system which allow geotechnical laboratories the complete automation of all test stages.
This apparatus have been designed to determine the resistance to shearing of all types of soil specimens including both consolidated and drained, undisturbed or remolded.
Soilmatic Direct Shear apparatus is an advanced system specifically designed to perform in a fully automated waythe following stages:
-Consolidation
-Drained Direct Shear
-Undrained Direct Shear
-Residual Direct Shear
In the direct shear test an increasing horizontal force is applied to the lower part of the soil specimen while the upper part is reacting against the shearing action.
From the measurement of this shearing action the shear strength of the soil is calculated.
After a first immediate general failure, the soil will stabilize, since the soil can still offer a residual strength.
Soilmatic direct shear apparatus is an electromechanical system powered by PID servomotors which apply high accuracy vertical and horizontal loads to a tested specimen without any human intervention for placing weights.
The Soilmatic system reads and processes vertical and horizontal force and displacement readings. Also manages the motors, the safety system and the test steps.
