S278 Shearmec - Electromechanical Shear Testing Machine

( Soil )
  • NF P094-071-2
  • AASHTO T236
  • UNI EN ISO 17892-10
  • ASTM D3080
  • STAS 8942-2-82
  • NF P094-071-1

Shearmec is a machine designed to perform direct and residual shear tests in a fully automatic and reliable way, including consolidation phases, and direct and residual shear.

The machine adopts robust electromechanical servo-controlled actuators which ensure a precise application of vertical and horizontal loads. The user-friendly interface allows the entire test to be set up while eliminating or reducing the need for manual intervention to perform both standardized tests or tests for research purposes.

Shearmec system includes:

  • S277-21 Load Cell, electric, 5 kN capacity
  • S277-22 Load Cell, electric, 10 kN capacity
  • S336-11 Linear vertical transducer, 10 mm travel
  • S336-12 Linear horizontal transducer, 25 mm travel
  • S277-31 Firmware activating 4 connectors for basic data acquisition

  • High performances for both standardized tests and tests for research purposes.
  • Cyber-Plus Progress for an accurate setting of the vertical load, thanks to an electromechanical actuator placed under the shear box.
  • Automatic calculation of the shear speed in compliance with standards.
  • Automatic load frame release for removing of the shear box.
  • Connection to SmartLab software for data processing and for remote control.
  • Possibility to perform tests 24/7.

Shearmec automatically calculates the appropriate shear velocity to be applied to the specimen by selecting the optimal consolidation parameter among t50, t90 and t100, improving efficiency and cost-effectiveness.
Thanks to its advanced firmware, Shearmec incorporates oedometer functions becoming extremely customizable during the consolidation phase.

It allows to:

  • Set different time acquisition windows for each load step;
  • Enable or disable settlement check and swelling check for each load step (NOTE: the condition set is the same for all steps).
