Ultimate and Fatigue Strength of Ship Hopper Knuckles
Author(s): Y.H. Kim, J.Y. Chung, J.K. Paik, W.S. Kim and D.H. Kim
Abstract:The aim of the present study is to investigate the characteristics of ultimate and fatigue strength of hopper knuckles in bulk cargo or LNG carriers. Ultimate strength test is undertaken on the hopper knuckle model subject to end moment. A series of fatigue tests are also carried out on the hopper knuckle models varying the level of the nominal stresses. The nonlinear finite element method is employed to examine distribution of hot spot stresses around weld toe and also the progressive collapse behavior of the model. A S-N curve is developed based on the fatigue test results.
