Estimating the forces acting on a high speed craft for structural assessment purposes is challenging due to complex combination of hydrodynamic loads. These include wave pressures, slamming pressures and their load effects at global ‘hull girder’ level. An experimental approach validate use established strip theory methods predicting pressure loads presented here. A series regular seakeeping te...

This article reviews the literature about the effects of specific non-traffic-related ambient noise sources on sleep that appeared in the last two decades. Although everybody is faced with noise of non-traffic and non-industry origin (e.g. sounds made by neighbors, talk, laughter, music, slamming doors, structural equipment, ventilation, heat pumps, noise from animals, barking dogs, outdoor eve...

Fig. 1. (A) Patient with posttraumatic enophthalmos and hypoglobus of the right eye. (B) Upward gaze limitation was noted on preoperative day 1. A B or a nerve sheath injury whereas direct damage to the optic nerve during dissection and insertion of implant materials is also possible. We report a case of a patient with postoperative traumatic optic neuropathy due to indirect nerve damage after ...

Abstract The inelastic deformation of a 30 m high-speed craft (HSC) subjected to slamming pressure is the main topic this research. In work, commercial software package ABAQUS FEA used predict structural behavior, especially in hull area under chine. Dynamic explicit solver simulations are done plastic deformation. Before principal analysis actual size ship structure model, numerical studies we...
