“…The present paper reports research work carried out to determine the design FCG curves of materials from ancient Portuguese riveted bridges, namely the Pinhão, Fão and Luiz I road bridges, built in 1906, 1891 and 1886, respectively, the Eiffel road/railway bridge (inaugurated in 1878) and the Trezói railway bridge (inaugurated in 1956). The design FCG curves were obtained using the procedure proposed by Gallegos Mayorga et al [2] and a comparison with design crack propagation curves proposed by BS7910 standard [3] is made. The authors have investigated the mechanical behaviour of those bridge materials, such as, metallographic, chemical composition, monotonic and fatigue behaviours of the materials of the old riveted steel bridges have been characterized [4][5][6][7].…”

In Portugal there is a number of old metallic riveted railway and highway bridges that were erected by the end of the 19 th century and beginning of the 20 th century, and are still in operation, requiring inspections and remediation measures to overcome fatigue damage. Residual fatigue life predictions should be based on actual fatigue data from bridge materials which is scarce due to the material specificities. Fatigue crack propagation data of materials from representative Portuguese riveted bridges, namely the Pinhão and Luiz I road bridges, the Viana road/railway bridge, the Fão road bridge and the Trezói railway bridge were considered in this study. The fatigue crack growth rates were correlated using the Paris's law. Also, a statistical analysis of the pure mode I fatigue crack growth (FCG) data available for the materials from the ancient riveted metallic bridges is presented. Based on this analysis, design FCG curves are proposed and compared with BS7910 standard proposal, for the Paris region, which is one important fatigue regime concerning the application of the Fracture Mechanics approaches, to predict the remnant fatigue life of structural details.

Abstract:The influence of material variability upon the multiaxial LCF assessment of engineering components is missing for a comprehensive description. In this paper, a probabilistic framework is established for multiaxial LCF assessment of notched components by using the Chaboche plasticity model and Fatemi-Socie criterion. Simulations from experimental results of two steels reveal that the scatter in fatigue lives can be well described by quantifying the variability of four material parameters . A procedure for choosing the safety factor for fatigue design has been derived by using first order approximation.

“…In contrast, the specimen after shot blasting exhibits a notable increase in the fatigue strength, which can be classified as FAT 160. To better the diagrammatic presentation and comparison, the linearized boundaries method outlined by Reference [14] was introduced, as shown in Figure 4b. It can be seen that a single slope represented by this method can be useful in the correlation with the test data, justifying the necessity of a global and simplified approach.…”

Abstract:The fatigue strength of Q345B steel plate with a central hole after shot blasting is studied herein. The improvement of fatigue strength related to the failure behavior is highlighted with due analysis of fatigue cracks initiation at the defect below the condensed surface induced by shot blasting. The effect of stress concentration is shown to be non-ignorable in the fatigue strength analysis. Codified fatigue categories in accordance with EN 1993-1-9 are used in drawing a comparison of studied fatigue behavior. Finally, an analytical model based on a modified reference model is proposed for the evaluation of the test fatigue strength results. It is demonstrated that the predicted results agree well with test data, since the stress ratio and the size of the defect as well as the stress concentration are appropriately considered.
