Abstract. Multilayer pipes composed of various materials improve partially the properties of a pipes system and are frequently used in praxis. To estimate the lifetime of these pipes the basic fracture parameters have to be measured. In the contribution a new approach to this estimation is presented. Special type of C-shaped non-homogeneous fracture mechanics specimen machined directly from the pipe was suggested, numerically analyzed and tested. Corresponding K values are calculated by FEM. Based on the presented results basic fracture mechanics parameters of materials used for multi-layer pipes construction can be estimated and the fracture toughness values of HDPE pipes material were obtained.
