Veryst's clients are often at the leading edge of industry, working with materials and applications that require highly precise and sophisticated testing techniques. Veryst developed a drop tower for conducting high strain rate uniaxial tension and compression tests to meet the demands of their clients and has been granted a United States patent on the design. Veryst's drop tower is a unique and versatile test system that can be used to measure accurately the high-rate stress-strain response of elastomers, thermoplastics, foams, engineering composites, thermosets, and biomaterials.
The system:
- is designed to minimize dynamic vibrations for all polymer materials, from soft elastomers and foams to stiff thermoplastic composites
- uses high speed video to record deformation history
- uses digital image correlation (DIC) to record the strain field
- uses dynamic load cells to record force measurements
- is capable of large deformation measurements, up to an engineering strain of 500% in tension
- includes custom software for combining the measured stress and strain data into a unified data file in csv-file format
- can be expanded with additional test fixtures designed for custom testing.
We also offer a temperature chamber as an optional supplement to the drop tower to enable testing at elevated and sub-ambient conditions. Many of our clients are interested in purchasing our customized test systems for their own use. Learn more.
