Özet

POM pipes are used to transport fluids. For this application, in-depth knowledge of the material's mechanical behavior and long-term performance is essential when subjected to mechanical stress. This article used an experimental approach based on macroscopic tests (thermal analysis technique for POM, tensile testing on notched axisymmetric specimens with measurement of the volume change), and complementary microscopic observations (MEB) to identify the cause of the damage. The results of the tests carried out at ambient temperature will be presented to show the influence of the type of control and the measurement principle (an assumption of homogeneous or isochoric deformation versus an assumption of transverse isotropic deformation) on the material's response.
