The coped regions restrict the ultimate capacity and cause unfavorable failure modes. The current study investigates the structural assessment of the coped section in offshore topsides while their use enhances operational safety for drilling and production. The structural evaluation is done through 2D digital image correlation (DIC) experiments to quantify the influence of various cope geometries. The DIC technique illustrated the strain and deformation measurements under different loading conditions for different coped geometry. The primary failure mode observed in local web buckling is characterized by noticeable lateral displacement and the development of buckling lines over the coped web. Studies showed the influence of the cope depth on the load-carrying capacity and buckling processes for different cope geometries. The results of the DIC analysis are strongly aligned with experimental data and finite element numerical results, suggesting this technique to the structural assessment of coped section.","PeriodicalId":16235,"journal":{"name":"Journal of Mechanical Science and Technology","volume":"47 1","pages":""},"PeriodicalIF":1.6,"publicationDate":"2024-08-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141883984","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A local model based on thermo elastic-plastic theory was established for inherent strain extraction. On this basis, an inherent strain model was built to simulate the deformation of long side and short side reciprocating deposition. Prediction accuracy and computational efficiency of the proposed inherent strain model were compared with the classic thermo elastic-plastic predictive and the experimental results. The results show that prediction error of the inherent strain model was 7.35 %. Though lower than the classic thermo elastic-plastic prediction (2.42 %), calculation time was reduced to 18 %∼41 % of that based on the thermo elastic-plastic model. Moreover, substrate distortion was well controlled when the scanning path was parallel to the fixed constraint surface since the residual stress was smaller.","PeriodicalId":16235,"journal":{"name":"Journal of Mechanical Science and Technology","volume":"21 1","pages":""},"PeriodicalIF":1.6,"publicationDate":"2024-08-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141883987","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While synchronous vibration can typically be mitigated during the blade design stage, the complete avoidance of non-synchronous vibration remains a challenge, prompting ongoing research efforts for predictive solutions. The study utilized an industrial gas turbine axial compressor with 1.5-stage blades for aerodynamic performance and flutter assessments. The calculated results were comprehensively compared with those of 1.5-stage scaled rig test. The comparative analysis demonstrated a strong alignment between predictions regarding aerodynamic performance and the presence or absence of flutter. Furthermore, unsteady flutter calculations were conducted for cases both with and without flutter, allowing for a detailed analysis of the factors contributing to flutter occurrence. Through this investigation, the study established methodologies for aeroelastic design and evaluation, along with a proposed approach for preventing flutter generation.","PeriodicalId":16235,"journal":{"name":"Journal of Mechanical Science and Technology","volume":"75 1","pages":""},"PeriodicalIF":1.6,"publicationDate":"2024-08-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141883978","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
