Hydrodynamic impact response, a flexible view

The popularity of high-speed craft is steadily increasing. Until now, much attention has been focussed on the hydrodynamic aspects of these craft. The structural design of these vessels is usually considered in a quasi static sense. However, due to the requirement of light ship structures, fast ship tend to be flexible. This flexibility combined...

Fatigue testing of large scale details of a large size aluminium surface effect ship

The paper presents the results of two large scale fatigue tests on a detail of an aluminium surface effect ship. The overall dimensions of the specimens were: length 4.8 m, height 3.2 m and width 1.5 m (equal to the main frame spacing). The specimens consist of an aluminium structure of welded plates (thicknesses up to 20 mm).

X-joints in composite sandwich panels

The small structural weight of fast large ships such as fast mono hulls or catamaran type of ships is of extreme importance to their success. One possible light weight structural solution is the sandwich panel with fibre reinforced laminates and a balsa, honeycomb or foam core. A severe obstacle for applying such panels is the design and...

Some considerations on design of ship structures and materials
