The growth of the fatigue crack is dependent on the crack growth resistance of the material as a bulk property. The fatigue crack growth properties of a material are usually described by the correlation between a crack propagation rate, and a corresp

The paper presents a methodology for the lifetime assessment of welded polymer pipes. A fracture mechanics analysis of a butt-welded joint is performed by simulating radial crack growth in the nonhomogenous region of the pipe weld. It was found that

This paper deals with assessment of conditions of fracture initiation in singular stress concentrations that are modeled by a bi-material notch composed of two orthotropic materials. Within the assessment of the stress concentrators, the stability cr

The failure mode termed long time brittle failure (due to slow crack growth – SCG) limits the lifetime of plastic pipes. There are now two main accelerated tests (PENT and FNCT) that enable us to estimate the lifetime of HDPE used in plastics pipes

Surface crack propagation in a thin soft protective layer on a massive stiffer substrate is analysed using generalised linear elastic fracture mechanics. The growth of the initial crack is considered in both forward and sideways directions and the in
