  1. 26. Hydroelasticity in Marine Hull Bottom Panels - Modeling and Characterization

    Författare :Ivan Stenius; Dan Zenkert; Pandeli Temarel; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fluid-structure interaction; hydroelasticity; hull-water impact; high-speed craft; slamming; explicit finite element methods; Vehicle engineering; Farkostteknik;

    Sammanfattning : The work in this thesis is concerned with the localized problem of hydroelasticity in marine panel-water impacts with an overall aim to increase the efficiency of high-speed craft by application of more refined methods in the structural design. The work mainly focuses on numerical modeling of the hydroelastic problem and therewith related aspects in the modeling and characterization of hydroelasticity. LÄS MER
