Paper presented at the The 31st International Ocean and Polar Engineering Conference, June 20–25, 2021
Paper Number: ISOPE-I-21-4189
... Abstract The external loads and ultimate load-carrying capacity are two important aspects to evaluate the safety and reliability of the ship. In this study, fluid-structural interaction calculation and model collapse test are combined together to obtain the ultimate strength of an aluminum...

Paper presented at the The 27th International Ocean and Polar Engineering Conference, June 25–30, 2017
Paper Number: ISOPE-I-17-665
... ABSTRACT The collapse pressures of cold formed pipes with rounded stress vs. strain curves in the circumferential direction are evaluated using collapse tests and finite element analyses. A novel prediction method to estimate the collapse pressures of cold formed pipes is discussed. A new...

... characteristics of SWATH under transverse load, the progressive collapse test of a steel model was conducted. Firstly, the test model was designed based on SWATH's structure and load characteristic. Then, the loading device was designed to apply load successively until the structural collapse. Finally...

Paper presented at the The Twenty-fifth International Ocean and Polar Engineering Conference, June 21–26, 2015
Paper Number: ISOPE-I-15-683
... Abstract In this study, we proposed an assessment method for shear buckling and collapse strength of a continuous stiffened panel with clarification of the boundary condition and its physical meaning. To validate this method, a series of collapse tests under combined in-plane shear and thrust...

... and mechanical pipe parameters are described. Then the influence of relevant pipe parameters on the collapse behavior was analyzed in a parameter study making use of a 3D Finite Element (FE) model of the collapse test. The investigated parameters were: pipe ovality, wall thickness and compressive stress-strain...

... a series of collapse tests. For the experiment, 720mm×720mm in section and 900mm in length of five box-girder models with stiffeners were prepared. Of the five, one has no damage and four have an ellipse shaped damage which represents the shape of bulbous bow of colliding ship. The damage size is different...
