Performance of a nongasketed flange joint under combined internal pressure and bending loading / Muhammad Abid in Journal of engineering mechanics, Vol. 136 N° 12 (Décembre 2010) 

Public ISBD [article]  in Journal of engineering mechanics > Vol. 136 N° 12 (Décembre 2010) . - pp.1519-1527 Titre : Performance of a nongasketed flange joint under combined internal pressure and bending loading Type de document : texte imprimé Auteurs : Muhammad Abid, Auteur ; Abdul Waheed Awan, Auteur ; David H. Nash, Auteur Année de publication : 2011 Article en page(s) : pp.1519-1527 Note générale : Mécanique appliquée Langues : Anglais (eng) Mots-clés : Bolts  Bending  Sealing  Internal  pressure. Résumé : Performance of a bolted flange joint is characterized mainly due to its “strength” and “sealing capability.” A number of analytical and experimental studies have been conducted to study these characteristics only under internal pressure loading. A very limited amount of work is found in the literature under combined internal pressure and bending loading. Due to the ignorance of this external loading, i.e., bending loading, the optimized performance of the bolted flange joint cannot be achieved. The present design codes do not address the effects of bending loading on the structural integrity and sealing ability. To investigate joint strength and sealing capability under combined loading, an extensive comparative experimental and numerical study of a nongasketed flange joint is carried out and overall joint performance and behavior is discussed. Actual joint load capacity is determined under both the design and proof test pressure with maximum additional external bending loading that can be applied for safe joint performance. In addition, as experimentally it is impossible to test different flange joint sizes under combined loading application, hence finite element model developed and verified with the experimental results, presented in this paper can be used as base to study the behavior for different nongasketed flange joint sizes for different classes under combined pressure and bending loading.
