Paper

The rules and regulations inherent to the design pressures and scantlings of high-speed powercrafts are numerous, and regularly reviewed. Recently, the new ISO 12215-5:2019 made notable changes to the way high-speed crafts are analysed, including extending the acceleration experienced up to 8 g in certain circumstances. Nevertheless, despite the multiple iterations and variety of regulatory...

Structures, loads, strength, materials

Paper

One of the most important design strategies for increasing the speed and/or efficiency of marine vehicles is that of weight reduction. This can be achieved by optimising structural design via judicious distribution of the most apt materials and via the application of innovative lightweight structures.
Sandwich structures are ideal candidates for structural lightening since they provide...

44. Non-linear FEA of AA 5083 welded jonts for high-speed marine vehicles

Structures, loads, strength, materials

Paper

The AA 50843 aluminium alloy is widely used in high speed marine vehicles thanks to its peculiar properties, such as adequate strength, lightness and excellent welding properties and resistance to corrosion, sea water and salty athmospheres. The aim of this scientific work was to develop and validate a procedure, starting only from hardness measurements, to predict the elastic-plastic...
