Defining the parameters of the strength and stiffness of soil respectively the following standards - LVS CEN ISO/TS 17892-8:2005 “Geotechnical investigation and testing - Laboratory testing of soil - Part 8: Unconsolidated undrained triaxial test”; LVS CEN ISO/TS 17892-9:2005 “Geotechnical investigation and testing - Laboratory testing of soil - Part 9: Consolidated triaxial compression tests on water satured soils”
*BENDER ELEMENTS measures the velocity of transverse and longitudal waves moving in the sample, defining the shear modulus G0, that characterizes the stiffness of the soil.
**The GDS LVDT Local Strain Transducers provide on-sample small strain measurements of axial and radial strain.
