K-Calibration of Specimens used for Lifetime Estimation of Multilayer Pipes

K-Calibration of Specimens used for Lifetime Estimation of Multilayer Pipes

Paper in proceedings (conference paper)

The determination of stress intensity factor for cracks in structures is a major subject in linear elastic fracture mechanics. In this work finite element calculations are applied in order to estimate the stress intensity factor values for a new type of non-homogenous C-type specimen. Based on the presented results fracture mechanics parameters of materials used for multi-layer pipes construction can be obtained.
