First, the microstructure and mechanical properties of the DMWJ are thoroughly analyzed. Next, the field subroutine “USDFLD” is used to establish a correlation between the non-uniformly distributed material mechanical properties and their spatial positions, thus characterizing the mechanical heterogeneity within the welded joint. Building upon this, a crack growth criterion based on the crack tip opening stress (CTOS) is developed using XFEM in conjunction with the UDMGINI subroutine. The influence of mechanical heterogeneity on stress corrosion cracking (SCC) propagation paths are then investigated. Finally, utilizing the identified crack propagation paths, the mechanical fields at the tip of the growing crack are analyzed under different loading conditions. The results indicate significant differences in the microstructure of local regions of the DMWJ, leading to an uneven distribution of local mechanical properties. Chemical composition gradients exist in the interface region, and significant fluctuations in mechanical properties are often observed near the interface. The material on the higher yield strength side has lower plastic constraints and crack resistance, which tends to result in a higher crack tip driving force. SCC cracks usually propagate towards the higher yield strength side, and the higher the yield strength, the longer the crack propagation length. Crack propagation induces the unloading process at the crack tip. As the crack extends, residual stresses or residual plastic strains are released and redistributed at the crack tip. A single tensile overload can relax the stress near the crack tip within a certain distance, reducing the strain rate.</div></div>","PeriodicalId":54946,"journal":{"name":"International Journal of Pressure Vessels and Piping","volume":"216 ","pages":"Article 105496"},"PeriodicalIF":3.0,"publicationDate":"2025-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143549475","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to investigate the fatigue life of elbow pipes and to quantify the reduction in fatigue life for component design. The fatigue test was conducted at room temperature using eight elbow specimens made of carbon steel. To suppress the ratcheting strain, only slight internal pressure was applied to detect crack penetration. Uniaxial and plate bending fatigue tests were also conducted using specimens taken from an elbow pipe of the same heat. The equivalent strain range at the crack initiation point, which was the inner surface of the crown, was successfully estimated from the measured strain using finite element analysis results. It was shown that the fatigue life obtained by the elbow test was shorter than that obtained by the axial and plate bending fatigue tests for the same equivalent strain range, and the reduction in fatigue life became more significant as the strain range increased. It was deduced that the ratcheting strain was not a major factor that caused the fatigue life reduction of elbow pipes. Then, the degree of the fatigue life reduction of the elbow specimens was quantified. The ratio of the fatigue life of the elbow specimen to that for uniaxial fatigue loading did not exceed 4 when the fatigue life of the elbow pipe was more than 120 cycles.</div></div>","PeriodicalId":54946,"journal":{"name":"International Journal of Pressure Vessels and Piping","volume":"216 ","pages":"Article 105491"},"PeriodicalIF":3.0,"publicationDate":"2025-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143549474","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Impression creep tests were conducted at 873–973 K under stresses ranging from 525 to 730 MPa. The BM and WM exhibited a true stress exponent of ∼5, indicating dislocation climb as the dominant creep mechanism, whereas HAZ showed a stress exponent of ∼3, suggesting dislocation glide as operating creep mechanism. Among the three zones, WM demonstrated superior creep resistance, with the BM exhibiting approximately 17.5 times higher creep velocity than WM at 923 K. The enhanced creep resistance of WM is attributed to its higher nickel content, which influences the activation energy for lattice self-diffusion. HAZ exhibited intermediate creep resistance between BM and WM.

The potential sliding between the steel tube and SCC, as well as between the SCC and segmental lining, has a substantial impact on the structural bearing capacity. Therefore, the finite element model of the composite lining was built based on the concrete damage plasticity model and the Coulomb friction model. The bearing ratio of each layer before and after fracture failure of the SCC were analyzed. It was found that the internal water pressure is mainly shared by surrounding rock. The bearing ratio of the steel tube is significantly lower than expected. Consequently, the design method of the composite lining was proposed based on the <em>d</em>/<em>E</em> of the CPDB (the ratio of the thickness <em>d</em> to its comprehensive elastic modulus <em>E</em>). The design philosophy of the novel composite lining is that the steel tube shares most of the internal water pressure.
