@TS Ik zou de romp even door laten rekenen door iemand met deze wetenschap in het achterhoofd maar komt vast goed.
Gezien de info van TS op LinkedIn is 'ie daar zelf heel best toe in staat.
Edit:
De nieuwe versie van de norm brengt wel wat wijzigingen met zich mee:
The main changes compared to the previous edition are as follows:
— clarification of the scope and of many definitions, dimensions, and assessment;
— definition of a theoretical hull/deck limit height ZSDT in Table 3;
— renaming of nGC into kDYN in Table 7;
— lowering of the values of kL in the aft part of the craft in Table 8;
— deletion of kAR min, to better consider large panels, mainly sandwiches, in Table 9;
— improvement of the values of kSUP in Table 10;
— modification of design pressures for motor and sailing craft in Tables 12 & 13;
— modification of design stresses introducing kBB and kAM factors in Tables 15 to 17;
— incorporation of requirements for work boats in Table 2, Clause 12 and Annex J;
— possibility to use a wider range of assessment methods detailed in Table 18;
— move of the previous assessment method (now called "simplified") in Annex A;
— improvements/clarification of the simplified method (panel assessment, hard chined sections, frameless sections, simple and double curvature, attached plating, requirements for core, etc.);
— development of Annex C for the determination of mechanical properties of composites; reminder in A.14 of the requirements of ISO 12215-9 on reinforcement of the hull in way of ballast keel attachment;
— new Annex I only recommending minimum thickness for single skin and sandwich that are no longer mandatory;
— new Annex J defining different types of commercial craft and workboats and their requirements;
— new Annex K defining loads induced by outboard engines;
— new Annex L proposing an application sheet of this document to explain how it has been used;
— for clarity, this edition generally uses tables to present formulas and requirements.
A list of all parts in the ISO 12215 series can be found in the ISO website.
NOTE The mechanical properties of ISO 12215-1 to -3 are largely superseded by the ones of this document.
Bijlage F, met mechanische eigenschappen van verschillende houtsoorten en gelamineerde platen (hoe je ze ook noemt
) is ook wel erg handig.
