| Educational objectives (expertise) | Students understand the fundamentals of different methods to determine the ultimate strength of marine structures. Ships and offshore structures are composed of welded plates and stiffened plate panels. Students apply appropriate models to introduce welding related initial deflections as well as residual stresses to structural components. The influence of initial imperfections due to welding on the buckling/plastic collapse behaviour of plates and stiffened plate structures is investigated. Students perform progressive collapse analyses exemplarily with the nonlinear finite element method to determine the ultimate strength of plate structures and they obtain a critical evaluation of the numerical results. |
