Veryst’s mechanical testing capabilities have been developed over the past decade and are motivated by the need for high quality data to characterize complex polymer behavior.  We tailor our test programs based on our deep understanding of polymer and material mechanics and the challenges complex material behaviors create for accurate simulations.  We recognize that many materials and in-service conditions require testing for which standards or well-documented procedures do not yet exist.  As a result, we have developed the expertise and infrastructure to design and implement customized testing solutions.

Veryst offers a wide range of services to characterize fully the material behavior relevant to your material and problem, including:

  • Standard tests (ASTM, ISO, etc.) on universal test frames
  • Decades of combined experience testing and calibrating material models

Veryst can also calibrate parameters for nearly any constitutive model available in commercial finite element codes.

Ideally, calibrated material models should be validated using a separate set of experiments designed to match the loading environment.  Veryst’s extensive background in polymer mechanics and finite element simulation also provides an ideal platform for verification and validation using standard and custom testing results.

Veryst can also assist with specimen preparation, creating standard and non-standard test specimens.  We have made specimens by conventional machining, waterjet machining, casting, and injection molding.

Tests by FEA Software

Veryst can specify a test program—a standard combination of tests—that captures your material’s response for use with a particular material model in a variety of finite element software packages. We have developed packages for many common constitutive models, but can customize the test plan to any model.

Specimen Preparation

Veryst can create test samples from raw materials, choosing the specimen preparation method that is most suitable for our clients' material and application.

FTIR Microscopy Analysis of Thermoplastic Solvent Bonding

Solvent bonding, although an effective way to join thermoplastics, can pose process challenges that reduce bond strength. Veryst uses FTIR microscopy to characterize the interface structure of solvent bonds, obtaining a “chemical image” of the solvent-bonded interface. The result is a full understanding of the bond and ways to improve its strength and reliability.

Impact Fracture Toughness of Adhesive Joints

Veryst developed a new test method for measuring fracture toughness under impact loading that does not require measurement of load or crack length. We have used this method to help clients in the automotive and electronics industry understand how adhesives fail under impact conditions.

Polymer Foam Testing & Modeling

Polymer foams may exhibit extreme strain rate-dependence due to their structure. The low stiffness means testing the materials at high strain rates is particularly difficult. Veryst has developed multiple test methods to test and model these materials.
