Ratcheting is not allowed in the current widely adopted ratcheting assessment method based on ratcheting boundary, which is conservative and only applicable to single cyclic load case. Whereas, the ratcheting analysis based on elastic-plastic finite element analysis cycle by cycle is computationally heavy and costly. In this paper, a simple and practical ratcheting assessment method based on cumulative damage is proposed. The method is abbreviated RACD method, which is an evaluation method of plastic ratcheting strain for prevention of ratcheting collapse and allows the structure to enter the ratcheting state. Moreover, it has low computational cost and can be applied to the ratcheting assessment of combined load cases. The validity of the RACD method has been verified by the Bree model and application example in this paper. It can be indicated that the linear damage accumulation theory is applicable to the cases where multiple load cases are applied independently and sequentially, but it is not suitable for the combination of multiple loads applied alternately. The load unit assessment method proposed in this paper can effectively deal with the ratcheting assessment problem for alternating combined load cases.</div></div>","PeriodicalId":54946,"journal":{"name":"International Journal of Pressure Vessels and Piping","volume":"213 ","pages":"Article 105389"},"PeriodicalIF":3.0,"publicationDate":"2024-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142759446","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}

At impact angles of 0° and 90°, the silty sand exerts only tangential stress and normal stress on the corrosion product film, respectively.

First, a pair of inspections is aligned at the boundaries between pipe joints. Pattern matching is then used to match individual defects on paired joints. Joint-boundary matching is a correspondence problem that can be described in terms of “drift”, which is the difference in odometry values at corresponding joint boundaries. Here, drift is formalized and characterized. It is used to describe current joint-boundary matching methods — interpolation, zippering, and direct odometry comparison. We use the drift formulation to illustrate why existing methods produce false matches (1) in the presence of poorly documented reroutes, (2) when there are nonlinearities in the odometry from pig speed changes, and (3) from other inspection problems. We develop a new evidence-based intuition for drift as the systematic bias of position-estimating state machines on inspecting pigs. This is followed by deriving a position-specific drift differencing distance metric using the first-order differencing of the drift. We show this value to be trend stationary. The results section compares the four metrics’ abilities to identify common joint-boundary matching challenges. We found that direct matching and interpolation are unreliable. These methods generate difficult-to-detect mistakes because they rely on a nearest-neighbor matching criterion. Zippering and drift differencing work much better. Both rely on pups in the vicinity of pipeline reconfigurations. They both fail when there are no pups or when a reconfiguration is large. Because zippering uses naive pattern-matching, it is subject to aliasing mistakes when non-corresponding joints are in analogous positions. In contrast, drift differencing, which is position-specific, is immune to this type of error. Finally, we show that the assumptions behind the derivation are valid for an example dataset.</div></div>","PeriodicalId":54946,"journal":{"name":"International Journal of Pressure Vessels and Piping","volume":"213 ","pages":"Article 105351"},"PeriodicalIF":3.0,"publicationDate":"2024-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142746778","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
