COMSOL offers an “inside look” at how Veryst’s engineers collaborate to produce accurate and reliable simulations.
Veryst has been granted a patent on our custom-designed drop tower for conducting high strain rate uniaxial tension and compression tests. This unique and versatile test system can be used to measure the high-rate stress-strain response of elastomers, thermoplastics, foams, engineering composites, thermosets, and biomaterials.
Dr. Jorgen Bergstrom et. al published an extended abstract on their work on testing and modeling the rate dependent behavior of polyether ether keytone (PEEK).
Ultra-high molecular weight polyethylene (UHMWPE) is used extensively in biomedical devices due to its mechanical properties, including high impact and wear resistance. Veryst developed an advanced thermomechanical constitutive model for UHWMPE where the microstructure of the material is represented using three structural domains that capture the experimentally-observed, nonlinear, time- and temperature-dependent response at small and large strains.
Dr. Mark Oliver and Dr. Sean Teller will be presenting and the NAFEMS World Congress, taking place May 19-22 in Salzburg, Austria. Dr. Oliver will be presenting on “Techniques for Inverse Calibration of Cohesive Zone Models”. Dr. Teller will be presenting on “Rate and Pressure-Dependent Failure Modeling of Thermoplastics“.

Researchers studying the anatomical and mechanical properties of ovine ribs asked Veryst to conduct high strain rate testing on our custom-built drop tower.
Veryst is pleased to introduce Bachir Abeid. Abeid’s primary focus is on computational modeling. His experience includes a wide range of mechanical testing, modeling, simulation, prototyping, and product development.
Dr. Sean Teller has joined Veryst Engineering, bringing extensive experience in the mechanical behavior of materials at low and high strain rates, including viscoelasticity, viscoplasticity, nonlinear materials, and fracture mechanics.
Dr. Scott Grindy presented “Accelerated Life Testing of Crosslinked Polyethylene (PEX) Materials” at the 2021 International Polyolefins Conference, which took place virtually February 23-24, 2021. The pre-recorded talk is now available online.
Dr. Matthew Hancock and Dr. Sean Teller spoke at the Pre Filled Syringes and Injectable Drug Devices East Coast conference held in Boston, MA. They talked about “Multiphysics Simulation and Testing in Combination Product Design & Verification: Reducing Patient Risk.” Afterwards, they participated in a panel discussion.
Dr. Scott Grindy was an instructor in the "Formulation Strategies Short Course" offered at the Adhesives and Sealants Council Annual Convention & EXPO, which took place in Louisville, Kentucky. Dr. Grindy discussed "Continuum and Fracture Mechanics based Testing and FEA of Bonded Joints."
Veryst’s new "In the Test Lab" webinar series focuses on polymer mechanics and experimental testing and features various experimental methods, test systems, and more. The first three webinars are now open for registration.
Dr. Mark Oliver spoke about “Applications of Digital Image Correlation in Adhesive Testing: Measuring High-Rate Fracture Toughness and Calibrating Cohesive Zone Models” at the 41st Annual Adhesion Society Meeting.
Dr. Mark Oliver made presentations on "Testing and Modeling the Mechanical Behavior of Flexible Adhesives" and on "Multiphysics Modeling of Underfill Flow and Cure During Thermocompression Bonding" at two industry conferences.
Dr. Mark Oliver gave a presentation entitled “Additively Manufactured Polymers: Using Testing and Simulation to Realize Reliable End-Use Parts” at AMUG 2018.
