Original Abstract

Numerical simulations of buried polymer pipes are necessary for the investigation of their long-term behavior. The demanded parameters may include just stress and deformations or even fracture mechanical parameters. Even though calculation of the buried pipe deformation and other parameters is quite a simple task, it usually runs into a fundamental problem of obtaining the material data for the characterization of the soil. These are hard to find, difficult to measure and, in the rare case they are available, they tend to be very scattered. Models using such data are then impossible to verify. This contribution proposes a workaround for this problem by connecting the numerical simulations with the available standards for the design of buried polymer pipes. The method is presented in several examples.
