Original Abstract

The problem of transferability of fracture mechanics parameters measured in laboratory on arc-shape specimen to real pipes is investigated in this paper. For this purpose the two-parameter description of crack behavior is used. The relevant numerical model based on the finite element method was used to calculate stress intensity factor K and T-stress as a function of the crack length for a both arc-shaped specimen and two-layer pipe. The applicability of the arc-shaped specimen for estimation of fracture mechanics parameters of HDPE material and their transferability to pipes are discussed. The results obtained contribute to reliability of pipes system.

Key words in English
