The purpose of this course is to broaden the basis for use of the finite element method for calculating static linear and non-linear behavior of complex structures and dynamic response of marine structures. The course is lectured in two parallel modules, respectively non-linear static and dynamic analysis. In the case of static analysis an introduction to the modeling of complex structures is given - exemplified by ship structure. Element formulations for linear analysis of prismatic and curved shell structures are shown, and an introduction to non-linear structural analysis caused by geometry and material behavior is given. There is also an introduction to practical modeling and analysis of structures with finite element method with appropriate software. The basis for the dynamic analysis is the static finite element method and d'Alemberts principle. The dynamic equilibrium equation is discussed in terms of virtual work, kinetic and potential energy and Rayleigh and Rayleigh-Ritz methods. The properties of the mass and damping matrices are discussed.
The course will give a brief overview of Ultimate load design principles and plastic capacity of sections Capacity estimate of tubular joints under axial, flexural and torsional buckling will be discussed.
