Pozycja Sensitivity Analysis of Steel Box-Section Girders.(Lodz University of Technology. Faculty of Mechanical Engineering. Department Division of Dynamics., 2013) Lis, Paweł; Kotełko, MariaThe paper deals with the load–carrying capacity stochastic variance based sensitivity analysis of thin–walled box–section girder subjected to pure bending. The lower– and uppe-r-bound load–capacity estimation is performed. The methodology is based on the Monte-Carlo method . The exemplary results are presented in diagrams and pie charts showing the sensitivity of load–capacity to different random input variables. The analysis is focused on the variance of the yield stress of the girder material and girder’s wall thickness. Some final conclusions, concerning an efficiency of the applied models and the sensitivity analysis are derived.Pozycja Static Buckling of FML Columns in Elastic-Plastic Range.(Lodz University of Technology. Faculty of Mechanical Engineering. Department Division of Dynamics., 2016) Kołakowski, Zbigniew; Kowal-Michalska, KatarzynaThe paper deals with the elasto-plastic buckling of thin-walled Fiber Metal Laminates short columns/profiles subjected to axial uniform compression. Structures of open and hollow (closed) cross-sections are considered build of at plate walls. Multilayered FML walls are considered as built of alternating layers of aluminum and fiber-glass composite. Three elastic-plastic theories are employed for constitutive relations description of aluminum layers i.e. fully elastic material behavior, the J2-deformation theory of plasticity and the J2 flow theory later both with Ramberg-Osgood formula application, whereas composite layers are assumed elastic within whole loading range. Some exemplary results determined with the application of own analytical-numerical method based on the Koiter's theory, in the Byskov and Hutchinson formulation are enclosed in the form of tables and plots.Pozycja Experimental buckling tests of FML profiles.(Wydział Mechaniczny.
