Numerical simulation of a harmonically loaded pipeline structure is used to establish the validity of the technique in the frequency domain. The analysis is carried out for a fixed-hinged pipe model. The results show that lack of coincidence between the vibration measurement points (VMPs) and the exciting force, or the use of only translational vibration measurements (TVMs) produce an approximate stress picture. The extent of the “error” in these cases is found to depend on the density of the VMPs and the proximity between these points and the exciting force location. A safety-related risk assessment is applied to find the minimum distance between measuring points that is needed to meet design codes reliability specifications.Copyright © 1998 by ASME<br /> <br /> <br /> == Original document ==<br /> <br /> The different versions of the original document can be found in:<br /> <br /> * [http://proceedings.asmedigitalcollection.asme.org/data/conferences/asmep/89948/705_1.pdf http://proceedings.asmedigitalcollection.asme.org/data/conferences/asmep/89948/705_1.pdf]<br /> <br /> * [http://asmedigitalcollection.asme.org/IPC/proceedings-pdf/doi/10.1115/IPC1998-2082/2507201/705_1.pdf http://asmedigitalcollection.asme.org/IPC/proceedings-pdf/doi/10.1115/IPC1998-2082/2507201/705_1.pdf],<br /> : [http://dx.doi.org/10.1115/ipc1998-2082 http://dx.doi.org/10.1115/ipc1998-2082]<br /> <br /> * [http://asmedigitalcollection.asme.org/pressurevesseltech/article-pdf/121/3/241/5561850/241_1.pdf http://asmedigitalcollection.asme.org/pressurevesseltech/article-pdf/121/3/241/5561850/241_1.pdf],<br /> : [http://dx.doi.org/10.1115/1.2883698 http://dx.doi.org/10.1115/1.2883698]<br /> <br /> * [https://asmedigitalcollection.asme.org/IPC/proceedings/IPC1998/40238/705/258170 https://asmedigitalcollection.asme.org/IPC/proceedings/IPC1998/40238/705/258170],<br /> : [https://proceedings.asmedigitalcollection.asme.org/proceeding.aspx?articleID=2572761 https://proceedings.asmedigitalcollection.asme.org/proceeding.aspx?articleID=2572761],<br /> : [https://micronanomanufacturing.asmedigitalcollection.asme.org/IPC/proceedings/IPC1998/40238/705/258170 https://micronanomanufacturing.asmedigitalcollection.asme.org/IPC/proceedings/IPC1998/40238/705/258170],<br /> : [https://gasturbinespower.asmedigitalcollection.asme.org/IPC/proceedings/IPC1998/40238/705/258170 https://gasturbinespower.asmedigitalcollection.asme.org/IPC/proceedings/IPC1998/40238/705/258170],<br /> : [https://asmedigitalcollection.asme.org/IPC/proceedings-pdf/IPC1998/40238/705/2507201/705_1.pdf https://asmedigitalcollection.asme.org/IPC/proceedings-pdf/IPC1998/40238/705/2507201/705_1.pdf],<br /> : [https://academic.microsoft.com/#/detail/2534463363 https://academic.microsoft.com/#/detail/2534463363]<br /> <br /> * [https://asmedigitalcollection.asme.org/pressurevesseltech/article/121/3/241/439085/On-the-Evaluation-of-Dynamic-Stresses-in-Pipelines https://asmedigitalcollection.asme.org/pressurevesseltech/article/121/3/241/439085/On-the-Evaluation-of-Dynamic-Stresses-in-Pipelines],<br /> : [https://pressurevesseltech.asmedigitalcollection.asme.org/article.aspx?articleid=1457688 https://pressurevesseltech.asmedigitalcollection.asme.org/article.aspx?articleid=1457688],<br /> : [http://pressurevesseltech.asmedigitalcollection.asme.org/article.aspx?articleid=1457688 http://pressurevesseltech.asmedigitalcollection.asme.org/article.aspx?articleid=1457688],<br /> : [https://academic.microsoft.com/#/detail/2161180198 https://academic.microsoft.com/#/detail/2161180198]<br /> <br /> <br /> <br /> DOIS: 10.1115/ipc1998-2082 10.1115/1.2883698</div>
