TP 304LN stainless steel straight pipes of 324 mm outer diameter under quasi-cyclic loading. The pipe specimens which were tested under load control failed by ductile tearing till sufficient crack length was reached followed by sudden rupture and collapse. For load values corresponding to 70%, 80%, 85% and 90% of the static load carrying capacity of the pipe, the number of cycles to final failure under quasi-cyclic loading were 120, 72, 41 and 21 respectively.\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\/ffl5a-773x1030.jpg\u0022 width=\u0022773\u0022 height=\u00221030\u0022 alt=\u0022Cyclic fracture test set-up on 324 mm OD stainless steel straight pipe\u0022 title=\u0022Cyclic fracture test set-up on 324 mm OD stainless steel straight 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\/ffl5b-773x1030.jpg\u0022 width=\u0022773\u0022 height=\u00221030\u0022 alt=\u0022Deflected shape of the pipe  after fracture test\u0022 title=\u0022Deflected shape of the pipe  after fracture test\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\/ffl5c.png\u0022 width=\u0022216\u0022 height=\u0022158\u0022 alt=\u0022Close-up views at notch location after fracture\u0022 title=\u0022Close-up views at notch location after fracture\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\/ffl5d.png\u0022 width=\u0022212\u0022 height=\u0022161\u0022 alt=\u0022Close-up views at notch location after fractureC\u0022 title=\u0022Close-up views at notch location after fracture\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\/hi\/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\/hi\/more\/node\/1824\/teaser\u0022 class=\u0022use-ajax\u0022\u003ERead less\u003C\/a\u003E\u003C\/li\u003E\n\u003Cli class=\u0022translation_en\u0022\u003E\u003Ca href=\u0022\/bimetallicnarrow-gap-welded-pipe-fracture-tests-under-cyclic-bending-load\u0022 title=\u0022Bimetallic\/narrow gap welded pipe fracture tests under cyclic bending load \u0022 class=\u0022translation-link\u0022 xml:lang=\u0022en\u0022\u003EEnglish\u003C\/a\u003E\u003C\/li\u003E\n\u003Cli class=\u0022translation_ta last\u0022\u003E\u003Ca href=\u0022\/ta\/bimetallicnarrow-gap-welded-pipe-fracture-tests-under-cyclic-bending-load\u0022 title=\u0022Bimetallic\/narrow gap welded pipe fracture tests under cyclic bending load \u0022 class=\u0022translation-link\u0022 xml:lang=\u0022ta\u0022\u003E\u0ba4\u0bae\u0bbf\u0bb4\u0bcd\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-1824","method":"addClass","arguments":["more-load node-teaser"]},{"command":"readmore_ajax","speed":"350"}]
