Many failures are due to third-party damage or poor joint preparation rather than failure under normal service loading conditions. While low failure rates should also be expected in the United States, there is insufficient historical data to extrapolate future failure rates. This project develops models to predict the long term performance prediction for PE pipes in the United States.    The objectives of this study were to (1) review the current field performance for polyethylene (PE) water pipelines; (2) review U.S. and international standards for PE water pipes; (3) review previous and state-of-the-art test methods and modeling techniques for service lifetime prediction of PE pipelines; (4) identify and measure relevant pipe properties that govern long-term field performance; and (5) develop and benchmark models to predict long-term field performance of PE pipes.     The experimental findings from this project demonstrate that the fracture performance of currently available PE materials is significantly improved from previous material grades. This indicates that the future performance of these current PE materials should not be assessed based on previous historical data held by water utilities. The simple equations provided from the physical probabilistic failure model in this study provide water utilities with a basis for estimating future failure rates. This information can be combined with knowledge of cost consequences of pipe failure and used to inform future asset management decisions, such as replacement planning and budget setting.","brand":"WoB","offers":[{"title":"- \/ - \/ -","offer_id":51857793253649,"sku":null,"price":0.0,"currency_code":"GBP","in_stock":true},{"title":"GB \/ NEW \/ GARDNERS","offer_id":51857793351953,"sku":"NGR9781843392071","price":0.0,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0784\/4072\/6801\/files\/9781843392071.jpg?v=1753829282"},{"product_id":"bergmans-linear-integral-operator-method-in-the-theory-of-compressible-fluid-flo-book-p-davis-9783709139950","title":"Bergman’s Linear Integral Operator Method in the Theory of Compressible Fluid Flow","description":"The reader who is somewhat acquainted with the field of compressible fluid flow hears much about Stefan Bergman's method of integral operators. It took many years for him to develop this method which is based primarily on the theory of analytic functions and particularly on the theory of)functions of two complex variables. The method, as a whole, is scattered throughout many papers in mathematical journals, and as a matter of fact, in its present state, is accessible only to those who are fully acquainted with mathematical literature. In one of their papers, Professors R. von Mises and M. Schiffer greatly simplified the method in the subsonic casco The purpose of the present work is to represent the method in all its variations in such a way that a theoretical engineer or an applied aerodynamicist can use it in practical applications. A professional mathematician will find the discussion too elementary for him. The parts of Bergman's presentation which are most interesting mathe- matically-the proofs-are mostly omitted in the present work. The emphasis was put upon the simplified representation of the final results and formulas, rather than upon the derivation of those formulas. In the preliminary remarks the author discusses various types of singularities in a very elementary way. The first two parts of the work deal with the subsonic case. In these sections the author followed mostly the paper of von Mises and Schiffer.","brand":"WoB","offers":[{"title":"GB \/ NEW \/ INGRAM","offer_id":52144788144401,"sku":"NLS9783709139950","price":0.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0784\/4072\/6801\/files\/9783709139950.jpg?v=1757590566"},{"product_id":"prayers-through-the-trimesters-book-p-davis-9798340144614","title":"Prayers Through the Trimesters","description":null,"brand":"WoB","offers":[{"title":"US \/ NEW \/ INGRAM","offer_id":53661266247953,"sku":"NIN9798340144614","price":0.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0784\/4072\/6801\/files\/9798340144614.jpg?v=1781438015"}],"url":"https:\/\/www.worldofbooks.com\/collections\/author-books-by-p-davis.oembed","provider":"World of Books ","version":"1.0","type":"link"}
