Abstract Due to an energy transition, crack growth under cyclic thermal loading becomes much more important in thick walled power plant components. Analytical descriptions of stress intensity factor behavior allow quick lifetime predictions. Those descriptions mainly exist for very short cooling down times. For that reason, the influence of cooling down times between 180 s and 3600 s on the stress intensity factor (SIF) of a cracked plate and hollow cylinder was investigated and different method...

Abstract Fracture mechanics parameters are used for experimental, numerical and analytical risk assessment of structural integrity and life of oil drilling rig welded pipe with a crack. As a simple analytical tool, the Failure Assessment Diagramme (FAD) has been applied to assess probability of pipe failure, using the ratio of linear elastic fracture mechanics parameter, KI, and its critical value, KIc, in relation to the ratio of applied stress and its critical value. Alternatively, the ratio o...

Abstract This paper presents an investigation of the potential of extended finite element method (XFEM) implemented in Abaqus standard software, with maximum principal strain and fracture energy as damage parameters for analysis of crack propagation and prediction of burst pressure in pipelines. Models of API 5L X60 pipe were calibrated first, using data from single edge notched tension test and then using burst pressures from 3 full scale tests. Both calibrations produced low fracture energy an...

Abstract In the context of structural integrity assessment of cracked Steam Generator Tubes (SGTs), the Failure Assessment Diagram (FAD) has been proposed as a modern tool able to reduce the conservativeness of traditional plastic limit load analyses. As different FAD failure curves are available in the literature, this paper presents a comparison between the so-called Options 1, 2 and 3 FAD curves derived for Inconel 690 and Incoloy 800 nuclear SGTs. Detailed Option 3 curves are obtained from e...

Abstract The failure assessment diagram (FAD) method is one of the mainstream methods for assessment of defects in steel pipes and girth welds. In this paper, the FAD curves based on Ramberg-Osgood model and tensile test requirements for steel pipelines from X52 to X100 are established with an accuracy of less than 3%. The results show that the generalized FAD curve is more conservative in evaluating high-grade defective pipelines than in evaluating low-grade pipelines. Based on the tensile test...

Abstract A thermo-mechanical peridynamic model using adaptive grid refinement is developed to investigate crack propagation in ceramics. Compared to a standard peridynamic model, using uniform grid, this approach allows to increase the resolution of analysis only in the critical zones. The performance of this approach in solving 2D thermo-elastic problems is examined and then it is applied to study the fracture of a ceramic disk under central thermal shock. Finally, the proposed approach is adop...

Abstract Steel is subject to hydrogen embrittlement (HE). This problem is relatively accurate for pipes transporting hydrogen pure or blended with natural gas. Therefore this problem has to be taken into account for the design and maintenance of pipe networks for this kind of transport. Design needs to modify the design factor for computing maximum working pressure in this case. Defect harmfulness needs specific tools for each type of defect which are the same as for pipe transporting natural ga...

Abstract Pipelines exposed to geo-hazards such as moving slopes, discontinuous permafrost, and other ground movements may be subjected to displacement-controlled loading, which may lead to significant plastic strains. This can potentially impact pipeline structural capacity and their leak-tight integrity. Traditional stress-based design methods may become uneconomical in the design of pipelines subjected to large plastic strain. In view of the extensive use of such pipelines, reliable calibratio...

Abstract To assess the reliability and performance of household liquefied petroleum gas (LPG) cylinder is important for safety standard. Such crack-like flaws in material of cylinder might lead to many serious catastrophes like fluid leakage and gas explosion. In this work, the failure assessment diagram (FAD) was determined according to the standard API 579 for inland produced LPG cylinders. A brand-new and used LPG cylinder of the same steel grade were investigated. Metallographic analyses, te...

Abstract The municipal water distribution systems across the world include a significant amount of cast-iron pipes. Many of the buried cast-iron pipes are over fifty years old and require rehabilitation. Municipalities decide on a rehabilitation solution between the replacement and re-use of the existing pipes based on the remaining strengths of the pipes. Fracture mechanics has appeared as the most viable tool for remaining strength assessment of the deteriorating pipes. However, a method of as...
