First, the validity of the strength models is verified by comparing their predictions with sandwich pipeline collapse test data and the corresponding model uncertainty factors are derived. Then, a parametric analysis of deterministic collapse strength predictions by models is conducted, illustrating insights of models\u2019 behaviour for a wide range of design configurations. Furthermore, the uncertainty among different model predictions is perceived at different configurations of outer and inner pipes and core thicknesses. A case study of a realistic sandwich pipeline is developed, and probabilistic models are defined to basic design parameters. Uncertainty propagation of models\u2019 predictions is assessed by the Monte Carlo simulation method. Finally, the strength model predictions of sandwich pipelines are compared to that of an equivalent single walled pipe.<\/jats:p>","DOI":"10.1115\/omae2021-63927","type":"proceedings-article","created":{"date-parts":[[2021,10,11]],"date-time":"2021-10-11T20:10:51Z","timestamp":1633983051000},"update-policy":"https:\/\/doi.org\/10.1115\/crossmarkpolicy-asme","source":"Crossref","is-referenced-by-count":0,"title":["Uncertainty in Collapse Strength Prediction of Sandwich Pipelines"],"prefix":"10.1115","author":[{"given":"U.","family":"Bhardwaj","sequence":"additional","affiliation":[{"name":"Instituto Superior T\u00e9cnico, Lisbon, Portugal"}]},{"given":"A.
