Testing

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:

  • Material model validation in multiaxial load cases
  • 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.

Accreditation

Veryst Engineering is an ISO/IEC 17025:2017 accredited testing laboratory. Learn about our accredited tests for polymers.

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.

High Strain Rate Testing and Modeling of Solid Polymers 2019

Oct 17-18, 2019
Foams, elastomers, and other polymers are often exposed to high strain rates and impact events. Due to the materials' strain-rate dependence, it is important to have accurate experimental data in order to select and calibrate a suitable material model. This class will demonstrate the use of Split Hopkinson bar tests and traditional uniaxial tests, and provide hands-on exercises for how to use the experimental data to calibrate suitable material models.

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 with our PolyUMod® library.
