Magnaflux Quasar RUSpec
The Magnaflux Quasar Resonant Ultrasound Spectrometer (RUSpec) is an integrated system for measuring material elastic constants and associated material properties. This is done by iteratively changing fundamental elastic constants in order to match predicted resonance patterns with measured patterns for a given material sample. (See FAQ)
Resonant Ultrasound Spectrometer (RUSpec)
Features
- Shear Modulus
- Young's Modulus
- Bulk Modulus
- Poisson's Ratio
- Density
- Longitudinal and Shear Velocities
Accuracy - High accuracy (greater than or equal to 0.1%) for large and small sample sizes. (See FAQ)
Testing Efficiency - Determines all independent elastic constants with one set of measurements. Can be used for isotropic, cubic, hexagonal, tetragonal, and orthorhombic structures.
Speed - Rapid determination of elastic constants vs. temperature. (For other than room temperature ranges see FAQ)
RUSpec Measures
- Resonant spectra for hard materials (metals, ceramics and some composites) and calculates independent Cij for rectangular parallelepipeds and cylinders. (See FAQ for additional detail)
- Sample sizes from millimeters to several centimeters.
- Within a temperature range from liquid helium to 1850+ degrees C.
The RUSpec product includes:
- RUSpec measurement system
