- TITLE: RELIABILITY OF PIPES WITH A DEFECT IN THE VOLUMETRIC HYDRAULIC SYSTEMS
- ABSTRACT: There has been composed a methodology for evaluating the reliability of oval section tubes in the presence of a flat elliptical defect in terms of fluctuations of temperature and pressure. Given methods allow quantitative to value residual longevity of the pipes with developing fatigue crack. The model based on the criterion of the critical crack opening. The calculation results on the model are in accordance with the experimental data obtained by other autors investigating the fracture of pipes and pressure vessels with longitudinal surface cracks.
