... generalized Navier–Stokes solver (GNS) with a volume of fluid (VOF) module ( 11 ) for air-water interface tracking. The predictive capability of GNS to compute complex wave deformation such as wave breaking is verified in Nakamura et al. ( 10 ). As explained later, GNS is further improved to account...

... on elastic-plastic fracture mechanics and plasticity theory was developed for that purpose. The analysis allows for load or deformation control situations. The results are shown in terms of curves of critical defect size versus the controlling variable, i.e., load or deformation. For each one of the several...

... to yield reliable predictions. Lastly, the finite element method was used to apply the wave-induced loads onto a comprehensive finite element structural model of the platform, yielding deformations and stresses. The Courant number was almost always less than 0.25 for all simulations. For the grid density...

...Yoshikazu Hashimoto; Naoto Hagiwara; Hiroshi Yatabe; Noritake Oguchi In this paper, the deformability of line pipe with local metal loss was examined. A full-scale experiment and a finite element (FE) analysis were carried out for line pipe with local metal loss subjected to an axial compressive...
