Dynamic properties of soil such as stress-strain characteristics have been recognized as crucial in many aspects of construction design. There are several types of geotechnical engineering problems associated with dynamic loading, some example includes: wave propagation, machine vibration, seismic loading, liquefaction, and transient cyclic loading. Our systems (Dynamic triaxial system [Dynatriax EmS], Resonant Column/Torsional Shear and Cyclic Simple Shear) are designed to reproduce in the laboratory these unusual in-situ events with the highest accuracy.
