This resonant column is equipped for isotropic and anisotropic tests using high quality electromechanical loading unit. Also this apparatus can be upgraded to perform experiments in unsaturated condition. The device can work under two different boundary conditions, so called free-free and fix-free conditions and has an adjustable drive mechanism for soft soils up to 20mm settlement. Dedicated Software to measure or calculate: Resonant Frequency(Hz): i) manually and ii)automatically /Shear stiffness (Strain dependent), G / Young’s modulus (E) / Density (ρ) / Poisson’s ratio (u) and Poisson’s ratio (u) and Damping (D) using three methods(Lissajous Figure, bandwidth method and free vibration Decay Method).
