Mechanical behavior of plastic components are not only dependent on the pure load or load case (e.g. bending vs. pure compression), but also on the loading time and temperature. The impact of these two factors will be discussed in this paper based on different testing results for polypropylene. Additionally a simplified viscoelastic model has been derived from that data to get a general idea for the engineering of plastic fills.
