Course content
The course deals with the load-carrying functionality, load-effect analysis and design of ships and marine structures. The following topics are addressed: Linear elastic analysis of shell- and plate-structures including numerical methods. Energy principles and virtual work. Plate buckling based on second order theory. Analyttical and energy-based numerical solution methods. Buckling of plate panels. Cross-section analysis. Design criteria related to yielding, buckling and fatigue.
Learning outcome
a) To be able to explain the main types of load-carrying components in floating hulls and their associated mechanical limit states
b) Demonstrate understanding of the mechanical basis for analysis of shells, and to be able to analyse the stress distribution in such components with focus on energy-based formulations
c) To outline the main steps of the Finite Element Method. To be able to explain the physical properties and the corresponding matrix formulations related to shell elements, including linearized geometric stiffness.
d) To be able to explain the difference between first- and second-order models for plate behavior and how this is reflected in the mathematical formulations
e) Demonstrate mastering of buckling analysis of plates and stiffened panels based on first principles. To show thorough knowledge of the differential equation, analytical solutions and numerical solutions based on energy methods
f) To be able to explain the principles underlying codified design rules related to buckling of stiffened plate panels
g) Mastering of methods for cross-section analysis in relation to torsion and shear stress distribution for open and closed cross-sections
h) To explain the steps related to fatigue life assessment of floating hulls based on the SN-curve approach and explain the concept of material class.

Further on evaluation
Portfolio assessment is the basis for the grade in the course. The portfolio includes a written exam (70%) and exercises (30%). The results for the parts are given in %-scores, while the entire portfolio is assigned a letter grade.
Examination papers will be given in English only. Students are free to choose Norwegian or English for written assessments.
If there is a re-sit examination, the examination form may change from written to oral.
For a re-take of an examination, all assessments during the course must be re-taken.
