Abstract
Polyoxymethylene (POM) is a semi-crystalline thermoplastic polymer with broad technical application. Microstructure after solidifying is strongly dependent on the thermodynamical conditions. As an outcome macroscopic observable time dependent behavior is complex and significantly non-linear. To describe creep behavior of POM a rheological model with five elements is utilized. Creep behavior of POM under monotonic loading and constant temperature conditions can be described in a satisfying manner according to experimental results. A three-dimensional generalization with a comparable backstress formulation will be given. Finally, influence of data scattering will be estimated applying statistical analysis.
