1. 1. Fatigue Assessment of Container Ships – a Contribution to Direct Calculation Procedures

   Författare :Zhiyuan Li; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; finite element analysis; container ship; warping stress; time-domain method; nonlinear panel method; full-scale measurement; side-shell structures; ship routing; stress concentration; fatigue;

   Sammanfattning : Within the field of marine structural engineering, the introduction of new materials and material classes, the development of production techniques and new design, and new requirements imposed by authorities are examples which justify a need for continuous revisit and update of fatigue assessment methodologies of marine structures. This thesis contributes to the development and improvement of fatigue assessment methodology for ship structures. LÄS MER

3. 2. RoPax Ship Collision – a Methodology for Survivability Analysis

   Författare :Per Hogström; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; non-linear FEA; failure modelling; uncertainty analysis; Crashworthiness; sheet metal failure; ship collision; damage stability;

   Sammanfattning : Throughout the world, ships are continuously being declared as total losses and 10 to 15% of these accidents are collisions between ships. The consequences of a collision are diverse and depend on the ship type, e.g. oil outflow in the case of damaged tankers or loss of stability in damaged passenger ships. LÄS MER
