Abstract

Završni rad bavi se analizom primarnog odziva brodske konstrukcije u ovisnosti o različitoj implementaciji valnog opterećenja na konstrukciju. U tu svrhu izrađena su tri pojednostavljena MKE modela različitih topologija glavnog rebra višepalubnog broda. Sljedeći korak bila je implementacija čvornih sila u tri MKE modela duž modela na dva različita načina po širini i visini presjeka. Zatim su se detaljno analizirale razlike u distribuciji smičnih i normalnih uzdužnih naprezanja.

Abstract (english)

This study deals with analysis of global structural response of ship construction depending on different implementation of wave load. There were made three simplified models with different topologies of main web frame for established geometry of main frame of multiple deck ship. Next step was to implement nodal forces on thee FEM models along full length of the model on two different ways of the discretisation. Finally, the differences in distribution of normal longitudinal and shear stresses were analysed in detail.
