Patent granted for Veryst's custom-built drop tower

October 8, 2024
Veryst Drop Tower--19A

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.
