Dynamic mechanical characterization of soft materials is essential in many industrial fields for both R&D and quality control (QC) applications. In polymer chemistry, this information plays a major role to formulate and standardize elastomeric materials and to target high-level viscoelastic performances.
High-frequency viscoelasticity of complex materials
Similarly, dynamic mechanical behavior of biological materials plays an important role in many biomedical applications. For example, understanding the relation between external forces (e.g. vehicle accidents, ballistic impacts, sports-related impacts) and traumatic brain injury caused by propagative shear waves is crucial for the development of efficient brain injury prevention systems.
Current technologies are limited to low and
Currently, mechanical testing instruments such as rheometers, dynamic mechanical analysers (DMA) or indentation systems are limited to measuring viscoelasticity in a frequency range typically below 200 Hz. This is a major limitation in several fields were dynamic loads and waves operate the kilohertz (kHz) frequency range.
RheoSpectrisTM C500+ measures viscoelasticity
As a response of this need Rheolution Inc. commercialises RheoSpectrisTM C500+, the first analytical instrument that measures viscoelastic properties of soft materials up to 2,000 Hz. RheoSpectrisTM C500+ performs hyper-frequency viscoelastic spectroscopy of materials using a new technology based on the shear wave induction of resonances (SWIR) of samples. The multiple sample holders of the instrument make easy the characterization of a wide range of materials having different geometrical shapes.

Technology of RheospectrisTM C500+
RheoSpectrisTM C500+ is an analytical instrument that non-destructively characterizes the viscoelastic properties (complex shear or Young moduli) of materials over a large frequency domain ranging between 10 and 2,000 Hz. The instrument uses a new technology called Shear Wave Induced Resonances. The sample may be confined into one of the following rigid sample holders: cylindrical, beam, slice or disk. Once the material sample is confined and fixed to the selected sample holder, this later is firmly attached to a mechanical unit that acts as a controlled dynamic actuator. When a test starts, the actuator vibrates vertically in order to transmit dynamic oscillations to the sample through the rigid sample holder. The excitation covers automatically the whole frequency range the user wants to explore.
An optical probe is used in RheoSpectrisTM C500+ to measure the sample’s response to the dynamic stimulus. The automatic positioning system rapidly and precisely focuses the measurement point. The sample’s response (i.e. its displacement as a consequence of the dynamic stimulus) will depends on its viscoelastic properties.
RheoSpectrisTM C500+ measures the shear complex modulus when a material is confined into the cylindrical or slice sample holders, while the beam and disk holders allow for the direct measurement of the Young complex modulus.
