Creep Testing of Polymers with Digital Image Correlation

Polymers are prone to deform slowly over long periods of time when subjected to applied load, a phenomenon known as creep. Over time, the deformation can grow so large that a polymeric part of a device or system no longer functions as intended, leading to product and material failures. This deformation is more pronounced at higher temperatures. Creep testing can be used to assess creep performance and can also be used for material comparisons in selecting the right material for an application.

In this video, Veryst measured creep strain during the test with digital image correlation (DIC) through the viewing window of an oven. Digital image correlation is a non-contact full-field strain measurement technique that can accurately measure large deformations at elevated temperatures, even for very soft materials such as plastics.
