Numerical Modeling of Ship Composite-Based on Aluminum Casting as Alternative Materials for Ship Building

Abstract:

The structure and construction of the ship is made of aluminum alloy, generally are of wrought aluminum alloys, when experiencing fatigue failure caused by a cracked vessel structure, is a serious problem. Reviewing of 'weakness' of wrought aluminum alloys for the ship, then in this study tries to provide material alternative for ship building is composite material based on aluminum casting AlSi10Mg (b) and reinforcing material silicon carbide (SiC), which has been in-treatment with the optimum composition 15%. Analysis of numerical computation with the help of ANSYS software version 2.00 to be made numerical modeling ship to ship aluminum EN AC-AlSi10Mg (b) and ship composite EN AC-AlSi10Mg (b)+SiC*/ 15p whether the material can be applied to building ship for see the distribution of stress . The results of the stress distribution in both of model numerical of ship, its value does not exceed the stress permits (sigma 0.2) and have a factor of safety above the minimum allowable limit, so it is safe to use. The overall, in numerical modeling, the ship material aluminum and ship composite materials can be used as an alternative material for ship building, however is still needed comprehensive testing in the field.Keywords: Aluminum casting ; ship building ; composite EN AC-43100(AlSi10Mg (b))+SiC*/15p; ANSYS ver.12,0
