An experimental study on the key fretting variables for flexible marine risers
O'Halloran, Sinéad; Harte, Annette M.; Shipway, Philip H.; Leen, Sean B. (Elsevier, 2017-07-02)This paper presents an experimental investigation into the effects of contact conformity, contact pressure and displacement amplitude on the gross-slip fretting behaviour grease-lubricated cylinder-on-flat contacts in the ... -
A global-local fretting analysis methodology and design study for the pressure armour layer of dynamic flexible marine risers
O'Halloran, Sinéad; Connaire, Adrian D.; Harte, Annette M.; Leen, Sean B. (Elsevier, 2019-09-19)In this paper, a global-local fretting design methodology for the pressure armour layer of flexible marine risers is outlined. This includes global dynamic riser analysis, geometrical and analytical sub-models and local ...
