Pozycja Static and Dynamic Thermomechanical Buckling Loads of Functionally Graded Plates.(Lodz University of Technology. Faculty of Mechanical Engineering. Department Division of Dynamics., 2013) Kowal-Michalska, Katarzyna; Mania, Radosław J.In the paper the buckling phenomenon for static and dynamic loading (pulse of finite duration) of FGM plates subjected to simultaneous action of one directional compression and thermal field is presented. Thin, rectangular plates simply supported along all edges are considered. The investigations are conducted for different values of volume fraction exponent and uniform temperature rise in conjunction with mechanical dynamic pulse loading of finite duration.Pozycja Stability and load carrying capacity of multi-cell thin-walled columns of rectangular cross-sections(Polskie Towarzystwo Mechaniki Teoretycznej i Stosowanej, 2009) Królak, Marian; Kowal-Michalska, Katarzyna; Mania, Radosław J.; Świniarski, JacekThe paper concerns theoretical, numerical and experimental analysis of the stability and ultimate load of multi-cell thin-walled columns of rectangular and square cross-sections subjected to axial compression (uniform shortening of the column). The theoretical analysis deals with the local and global stability of multi-cell orthotropic columns of a rectangular profile with rectangular cells. It has been shown that for a multi-cell column made of the same material and having the same cross-section area, the value of local buckling stress of the column walls grows rapidly with an increase of the cell number. The experiment conducted for isotropic columns has also proved a significant growth of the ultimate load with the increase of the cell number. The paper gives some conclusions which can be useful in design of thin-walled box columns.Pozycja Static and dynamic buckling of functionality graded plates subjected to thermomechanical loading(Politechnika Łódzka.
