Testing at Elevated/Sub-ambient Temperatures

Polymers are used increasingly in elevated temperature applications such as seals and biomedical implants.  Data on the mechanical behavior of polymer materials at elevated temperatures is not available or is inadequate to make informed design decisions.  Design and simulation engineers require mechanical testing at a range of temperatures to design products used at these temperatures.

Veryst works with its clients to design efficient, cost-effective test programs that capture a material’s temperature-dependent response with a minimum number of tests.  Veryst supplies its clients with a data-set sufficient for understanding a material’s behavior at a specified range of temperatures from -80ºC – 280ºC using strategies involving non-standard loading histories and loading modes.  An example for polyether ether ketone (PEEK) is show below.  This data set is sufficient to calibrate nonlinear material models for use in finite element simulations.

Temperature-dependent stress-strain and relaxation behavior gathered for PEEK.
This data can be used to calibrate an advanced non-linear constitutive model for finite element simulations.
