Response of a tank under blast loading -- part I / D.H. Duong in European journal of environmental and civil engineering, Vol. 16 N° 9 (special issue) (Octobre 2012) 

Public ISBD [article]  in European journal of environmental and civil engineering > Vol. 16 N° 9 (special issue) (Octobre 2012) . - pp. 1023-1041 Titre : Response of a tank under blast loading -- part I : Experimental characterisation of blast loading arising from a gas explosion Type de document : texte imprimé Auteurs : D.H. Duong, Auteur ; J.L. Hanus, Auteur ; L. Bouazaoui, Auteur Année de publication : 2012 Article en page(s) : pp. 1023-1041 Note générale : Génie Civil Langues : Français (fre) Mots-clés : Blast  load  Shock  wave  Dynamic  Buckling  Cylinder  Simplified  analysis  Numerical  methods Résumé : In explosion--structure interaction problems such as the dynamic response of a cylindrical shell to a blast load, an accurate prediction of both blast loading and geometrical and/or material nonlinear structural response still remains a hard challenge. Furthermore, closed-form simplified analytical or semi-empirical models provide faster and more versatile tools of analysis. To assess the validity of simplified analytical models as reliable design tools and to check the conformity of numerical simulations, experimental studies are carried out at small scale to give benchmark results. A first study presents blast test results performed on rigid instrumented cylinders to quantify the loading in terms of time and space pressure distribution.

Duong, Auteur ; J.L. Hanus, Auteur ; L. Bouazaoui, Auteur Année de publication : 2012 Article en page(s) : pp. 1042-1057 Note générale : Génie Civil Langues : Français (fre) Mots-clés : Blast  load  Dynamic  Buckling  Cylinder  P-I  diagrams  Numerical  methods  Reliability Résumé : The problem of dynamic buckling of thin cylindrical tanks subjected to an external blast caused by an accidental external gaseous detonation is studied in this paper. A study is performed on flexible cylinders at a reduced scale to quantify the structural response. Simplified semi-analytical models based on Donnell's equations and critical imperfection amplification thresholds are used to provide damage predictions. Numerical results are compared to experimental ones which shows a qualitative good agreement. Finally, a reliability analysis on a real atmospheric oil tank is performed and compared with damage diagrams in the form of pressure impulse curves and safety recommendations.
