Cyclic simple shear

Dynamic shear test apparatus for soil beahavior prediction under dynamic conditions

Cyclic simple shear 31-WF7500
Sample in the cyclic simple shear 31-WF7500
Scheme of the sample in the Cyclic simple shear 31-W7500
Set up parameters: This stage of the software allows you to select the type of test parameters you wish to carry out for example: Consolidation stage force pressure Shear stage axial mode to be controlled in stress or constant height. Shear stage lateral mode to be controlled in force or displacement with choice of wave shape. Shear rate speed. Test termination on cycle counts or % axial strain.
Consolidation: This stage shows the consolidation forces being applied to the sample. -- Graph displays Axial stress against time. Induced pore pressure against time. Axial force against time. Shear force against time.
Cyclic shear: This stage shows the dynamic forces/ displacements being applied to the sample. -- Graph displays Axial stress against time. Induced pore pressure against cycles. Axial force against time. Shear force against time.
Rate shear: This stage shows the rate shear being applied to the sample. -- Graph displays: Axial stress against time. Induced pore pressure against time. Axial force against time. Shear force against time.
