DSS Direct Simple Shear System
Advanced fully automatic simple-shear apparatus with two high quality servomotor drives for static, cyclic and dynamic shear loads up to 10 kN.
This electro-mechanic, dynamic, cyclic machine is a high-quality but robust device, both mechanically and electronically. This includes a highly stiff frame and actuator system to compensate for any deformations during static or cyclic loading.
The machine includes two high-quality servomotor drives to perform vertical load tests (static and dynamic).
- Highly stiff frame and actuator system to compensate for any deformation in static or cyclic loading
- Suitable for drained and un-drained direct or simple shear tests
- Double side horizontal and vertical ball-bearing guided cross-head for load piston and shear boxes
- Closed-loop controlled height for constant volume conditions (K0-Conditions)
- Closed-loop control of strain, load and displacement for static and cyclic shear stresses Sophisticated robust construction combined with high-quality mechanic and electronic components
- The sample is mounted with a rubber-membrane (spiral wire or Teflon coated rings) and is connected to a tilt free, parallel guided lower shear box and a tilt free, vertical parallel-guided load piston
- Highly-accurate displacement transducers for settlement and displacement (strain)
