High-temperature uniaxial creep apparatus in the Rock Rheology Lab. This is our primary apparatus for investigation of the mechanical properties of rocks. It was designed in collaboration with Physik Instrumente for high resolution mechanical tests, implementing both electromechanical and piezoelectric actuators. Maximum operation temperature is 1500°C with controlled chemical environments. Key behavioral targets are viscoelasticity, anelasticity, seismic attenuation, and viscous creep.
