Even with the latest computer-aided modelling technologies, finite element modeling of branch connections using three-dimensional (3-D) solid elements is the only way to accurately determine the stress distributions local to the weld toes of branch connections.\u003c\/p\u003e\n\n\u003cp\u003eThis report describes work to access the applicability of linear elastic fracture mechanics (LEFM) principles to a saddle-pad reinforced branch connection modelled using 3-D elements, The effort concentrated on determining the amount and location of plastic zones resulting from different combinations of service loadings. Loadings considered include pressurization to 72% of the specified minimum yield strength with the addition of main pipe end tension or compression. The effect of contact and different material models were also quantified.\u003c\/p\u003e","brand":"PRCI Store","offers":[{"title":"Default Title","offer_id":44362014031950,"sku":"15085","price":249.0,"currency_code":"USD","in_stock":true}],"url":"https:\/\/prci-store.myshopify.com\/products\/l51737-development-of-modeling-procedures-for-branch-welds","provider":"PRCI Store","version":"1.0","type":"link"}
