Global and local instability of thin-walled columns beyond the proportional limit
(Wydawnictwo Politechniki ŁódzkiejLodz University of Technology Press, 1997)
The problem of global and local stability in the inelastic range for thin-walled columns is
examined on the basis of the defonnation theory and the incremental theory of plasticity. Columns of closed and open cross-sections ...
Nośność graniczna cienkościennych słupów z centralnymi żebrami pośrednimi w ramach drugiego rzędu nieliniowego przybliżenia
(Wydawnictwo Politechniki ŁódzkiejLodz University of Technology Press, 1997)
W pracy przeanalizowano interakcyjne wyboczenie cienkościennych słupów wzmocnionych
żebrami pośrednimi. Żebra modelowano płytami. Przyjęto, że słupy są swobodnie podparte na obu
końcach. Zastosowano drugi rząd nieliniowego ...
Static and dynamic interactive buckling of composite columns.
(Polskie Towarzystwo Mechaniki Teoretycznej i Stosowanej, 2009)
The static and dynamic problem of interaction of global buckling modes in compressed columns with complex open and closed cross-sections was considered in the paper. The columns made of laminate composites were assumed to ...
Some aspects of the axial extension mode in an elastic thin-walled beam-column.
(Polskie Towarzystwo Mechaniki Teoretycznej i Stosowanej, 2012)
The present paper deals with the influence of the axial extension mode on static and dynamic interactive buckling of a thin-walled beam-column with imperfections subjected to uniform compression when the shear lag phenomenon ...
Static and dynamic interactive buckling regarding axial extension mode of thin-walled channel
(Polskie Towarzystwo Mechaniki Teoretycznej i Stosowanej, 2010)
The present paper deals with an influence of the axial extension mode on static and dynamic interactive buckling of a thin-walled channel with imperfections subjected to uniform compression when the shear lag phenomenon ...
Free and forced oscillations of Timoshenko beam made of viscoelastic material.
(Polskie Towarzystwo Mechaniki Teoretycznej i Stosowanej, 2011)
Dynamics of Timoshenko's beam made of a viscoelastic material is studied. Dimensionless equations of motion are obtained, depending only on two parameters, one of which relates to the shear flexibility and the second – to ...
Comparision of Numerical Results with Known Solutions of Buckling Problem of Pressured Shallow Spherical Shells.
(Lodz University of Technology. Faculty of Mechanical Engineering. Department Division of Dynamics.Wydawnictwo Politechniki Łódzkiej. Wydział Mechaniczny. Katedra Dynamiki Maszyn., 2016)
Buckling problem of pressured shallow spherical shells is studied numerically for two types of finite elements: axisymmetric and non–axisymmetric. A very good correspondence of obtained results and known solutions is ...
Local Buckling of Thin-Walled Column of Square Cross-Section Made of In-Plane Coupled Laminate.
(Lodz University of Technology. Faculty of Mechanical Engineering. Department Division of Dynamics.Wydawnictwo Politechniki Łódzkiej. Wydział Mechaniczny. Katedra Dynamiki Maszyn., 2016)
The non–symmetric, general laminate exhibits different types of coupling between the extension, shearing, bending and twisting. For practical reasons, the in–plane coupled laminate is a particularly interesting. In this ...
Static Buckling of FML Columns in Elastic-Plastic Range.
(Lodz University of Technology. Faculty of Mechanical Engineering. Department Division of Dynamics.Wydawnictwo Politechniki Łódzkiej. Wydział Mechaniczny. Katedra Dynamiki Maszyn., 2016)
The 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 ...
Damping behaviour of thin-walled composite columns under impact in-plane loading
(Politechnika Łódzka. Katedra Wytrzymałości Materiałów i Konstrukcji., 2012)
In this paper the analysis of the damping behaviour of thin-walled composite columns with open stiffened cross-sections subjected to in-plane pulse loading is described. The pulse loading of a rectangular shape is ...
