Abstract (Croatian)
U ovom se izvješću sažimaju napori u utvrđivanju svojstava materijala ugrađenih u brodski trup u suradnji Laboratorija za eksperimentalnu mehaniku, Zavoda za brodogradnju i pomorsku tehniku i hrvatskih brodogradilišta. Svojstva materijala u brodogradnji se obično definiraju u fazi preliminarnog projektiranja i kao takva se koriste kroz cijeli proces projektiranja, konstruiranja, proizvodnje, gradnje i službe broda. Nova iskustva pak pokazuju da neka svojstva materijala mogu značajno odstupati od nazivnih vrijednosti. Uzorci materijala su odabirani tijekom izgradnje u brodogradilištu i podvrgavani vlačnom pokusu, pokusima zamora i udarne žilavosti. Izvješće razmatra utjecaje svojstava ugrađenih materijala s obzirom na zahtijevana svojstva prema Pravilima na lokalnu, globalnu i graničnu čvrstoću broda. Zaključak podržava ideju izvješća da brodovi zaslužuju individualizirano utvrđivanje čvrstoće kakva stvarno jest na osnovi sustavno prikupljanih i posebno ispitanih ugrađenih materijala.
Abstract
This report summarizes the efforts in testing of material built in the ship’s hull which are performed in cooperation among the Laboratory for experimental mechanics, the Department of naval architecture and ocean engineering of the Faculty of mechanical engineering and naval architecture in Zagreb and Croatian shipyards. Recent experiences and observations indicated that some material properties might significantly deviate of the nominal or declared values.. Material specimens are selected during the ship production process in the shipyard and submitted to tensile testing, fatigue tests and Charpy impact tests in the laboratory. The report considers the influences of particular ‘in-built’ material properties with respect to the Rule requirements on local, global and ultimate strength of ships. The conclusion supports the stirring idea of this report that a ship deserves individualized assessment of the “as-built” ship hull strength based on the systematically collected and measured ‘in-built’ material properties.
