The internal pressure for all the straight pipes was ranging from 25 MPa to 45 MPa and in the case of elbows the internal pressure was varied for different elbows, ranging from 27.6 MPa to 39.2 MPa. Cyclic bending load was applied on the specimens by subjecting them to different levels of load-line displacement. The straight pipes failed either by occurrence of through-wall crack accompanied by simultaneous ballooning, or bursting with simultaneous ballooning. All the elbows failed by occurrence of through-wall crack accompanied by simultaneous ballooning. Ratcheting behaviour of straight pipes and elbows were compared and it was generally inferred that ratcheting was more pronounced in straight pipes than in elbows\u003C\/p\u003E\n\u003C\/div\u003E\u003C\/div\u003E\u003C\/div\u003E\u003Cdiv class=\u0022field field-name-field-project-images field-type-image field-label-above\u0022\u003E\u003Cdiv class=\u0022field-label\u0022\u003EProject Images:\u0026nbsp;\u003C\/div\u003E\u003Cdiv class=\u0022field-items\u0022\u003E\u003Cdiv class=\u0022field-item even\u0022\u003E\u003Cimg typeof=\u0022foaf:Image\u0022 src=\u0022https:\/\/serc.res.in\/sites\/default\/files\/ffl4a.png\u0022 width=\u0022558\u0022 height=\u0022334\u0022 alt=\u0022Ratcheting experimental set-up on 168 mm OD stainless steel pipe\u0022 title=\u0022Ratcheting experimental set-up on 168 mm OD stainless steel pipe\u0022 \/\u003E\u003C\/div\u003E\u003Cdiv class=\u0022field-item odd\u0022\u003E\u003Cimg typeof=\u0022foaf:Image\u0022 src=\u0022https:\/\/serc.res.in\/sites\/default\/files\/ffl4b.png\u0022 width=\u0022269\u0022 height=\u0022319\u0022 alt=\u0022Ratcheting experimental set-up on 168 mm OD stainless steel elbow\u0022 title=\u0022Ratcheting experimental set-up on 168 mm OD stainless steel elbow\u0022 \/\u003E\u003C\/div\u003E\u003Cdiv class=\u0022field-item even\u0022\u003E\u003Cimg typeof=\u0022foaf:Image\u0022 src=\u0022https:\/\/serc.res.in\/sites\/default\/files\/ffl4c.png\u0022 width=\u0022270\u0022 height=\u0022317\u0022 alt=\u0022Occurrence of through-wall crack indicated by a sharp water jet\u0022 title=\u0022Occurrence of through-wall crack indicated by a sharp water jet\u0022 \/\u003E\u003C\/div\u003E\u003C\/div\u003E\u003C\/div\u003E\u003Cdiv class=\u0022field field-name-field-project-enterprise-categor field-type-taxonomy-term-reference field-label-above clearfix\u0022\u003E\u003Ch3 class=\u0022field-label\u0022\u003EProject Enterprise Category: \u003C\/h3\u003E\u003Cul class=\u0022links\u0022\u003E\u003Cli class=\u0022taxonomy-term-reference-0\u0022\u003E\u003Ca href=\u0022\/ta\/research-expertise\/fatigue-fracture\u0022 typeof=\u0022skos:Concept\u0022 property=\u0022rdfs:label skos:prefLabel\u0022 datatype=\u0022\u0022\u003EFatigue \u0026amp; Fracture\u003C\/a\u003E\u003C\/li\u003E\u003C\/ul\u003E\u003C\/div\u003E  \u003C\/div\u003E\n\n      \u003Cdiv class=\u0022link-wrapper\u0022\u003E\n      \u003Cul class=\u0022links inline\u0022\u003E\u003Cli class=\u0022node-readless first\u0022\u003E\u003Ca href=\u0022\/ta\/more\/node\/2889\/teaser\u0022 class=\u0022use-ajax\u0022\u003ERead less\u003C\/a\u003E\u003C\/li\u003E\n\u003Cli class=\u0022translation_en\u0022\u003E\u003Ca href=\u0022\/studies-ratcheting-behaviour-pressurised-pipes-and-elbows\u0022 title=\u0022Studies on ratcheting behaviour of pressurised pipes and elbows\u0022 class=\u0022translation-link\u0022 xml:lang=\u0022en\u0022\u003EEnglish\u003C\/a\u003E\u003C\/li\u003E\n\u003Cli class=\u0022translation_hi last\u0022\u003E\u003Ca href=\u0022\/hi\/studies-ratcheting-behaviour-pressurised-pipes-and-elbows\u0022 title=\u0022Studies on ratcheting behaviour of pressurised pipes and elbows\u0022 class=\u0022translation-link\u0022 xml:lang=\u0022hi\u0022\u003E\u0939\u093f\u0928\u094d\u0926\u0940\u003C\/a\u003E\u003C\/li\u003E\n\u003C\/ul\u003E    \u003C\/div\u003E\n  \n  \n\u003C\/div\u003E","settings":null},{"command":"invoke","selector":"#node-2889","method":"addClass","arguments":["more-load node-teaser"]},{"command":"readmore_ajax","speed":"350"}]
