Polymers exhibit significant temperature-dependent mechanical response. Veryst tested a PEEK material at multiple temperatures and calibrated the PolyUMod® Three Network (TN) material model for finite element simulation.
This case study demonstrates the testing and calibration of a polycarbonate material at a high strain rate of 1000 sec-1. The testing was done with the Split Hopkinson Pressure Bar (SHPB) system and the calibration is performed with Veryst Engineering’s MCalibration® software.
PEEK materials are increasingly used in a variety of industries with elevated temperature applications. This example shows how Veryst Engineering developed a temperature-dependent, nonlinear model of PEEK behavior for use in commercial FEA codes.
Veryst has extensive experience selecting and calibrating material models to capture the most important aspects of material behavior for your specific material and conditions during use. Using MCalibration®, a software tool originally developed
Veryst has designed six test programs specifically for MSC.Marc material models.
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
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.
