Finite element analysis
|Publication Date:||1 August 2020|
This class guideline describes the scope and methods required for structural analysis of ships and the background for how such analyses should be carried out. The class guidelines application is based on relevant rules for classification of ships.
The DNV GL rules for classification of ships may require direct structural strength analyses as given in the rules.
Structural analyses carried out in accordance with the procedure outlined in this class guideline will normally be accepted as basis for plan approval.
Where the text refers to the rules for classification of ships, the references refer to the latest edition of the rules for classification of ships.
In case of ambiguity between the rules and the class guideline, the rules shall be applied.
Any recognised finite element software may be utilised provided that all specifications on mesh size, element type, boundary conditions etc. can be achieved with this computer program.
If wave loads are calculated from a hydrodynamic analysis, it is required to use recognised software. As recognised software is considered all wave load programs that can show results to the satisfaction of DNV GL.
