Wille – Resonant Column Device
This Resonant Column is a high quality apparatus for measuring the low-shear Strain (less than 0.001%) or elastic modulus and damping properties of materials (e.g. wide variety of soils, rocks, Asphalt, etc) for solid- or hollow cylindrical samples under confined condition.
