1Nonlinear Bend Stiffener Analysis Using A Simple Formulation and Finite Element Method显示文摘Flexible marine risers are commonly used in deepwater floating systems.Bend stiffeners are designed to protect flexible risers against excessive bending at the connection with the hull.The structure is usually analyzed as a cantilever beam subjected to an inclined point load.As deflections are large and the bend stiffener material exhibits nonlinear stress-strain characteristics,geometric and material nonlinearities are important considerations.A new approach has been developed to solve this nonlinear problem.Its main advantage is its simplicity;in fact the present method can be easily implemented on a spreadsheet.Finite element analysis using ABAQUS is performed to validate the method.Solid elements are used for the bend stiffener and flexible pipe.To simulate the near inextensibility of flexible risers,a simple and original idea of using truss elements is proposed.Through a set of validation studies,the present method is found to be in a good agreement with the finite element analysis.Further,parametric studies are performed by using both methods to identify the key parameters and phenomena that are most critical in design.The most important finding is that the common practice of neglecting the internal steel sleeve in the bend stiffener analysis is non-conservative and therefore needs to be reassessed.TONG Dong Jin LOW Ying Min SHEEHAN John M 2011China Ocean Engineering2011,25,4:6

12Colonic perforation in Behet's syndrome显示文摘A 17-year-old gentleman was admitted to our hospital for headache, the differential diagnosis of which included Behet's syndrome (BS). He developed an acute abdomen and was found to have air under the diaphragm on erect chest X-ray. Subsequent laparotomy revealed multiple perforations throughout the colon. This report describes an unusual complication of Behcets syndrome occurring at the time of presentation and a review of the current literature of reported cases.Catherine M Dowling Arnold DK Hill Carmel Malone John J Sheehan Shona Tormey Kieran Sheahan Enda McDermott Niall J O’Higgins 2008World Journal of Gastroenterology2008,14,42:0
