“…They offer a solution to the problem of non-linear stability of the investigated thin-walled structures using experimental and numerical methods [15][16][17][18][19][20]. The investigations of critical and post-critical states as well as the damage of thin-walled composite columns are reported, for instance, in the works [6,7,14,15,[21][22][23][24][25][26][27][28], where the authors present different methods for describing the problem of nonlinear stability Fig. 1 Post-critical equilibrium paths of a plate without initial deflections and of a real structure and validate the developed numerical models in the experimental tests.…”

“…The problem of stability of thin-walled structures under operational static loads was investigated for instance in [6][7][8][9][10][11][12][13][14], where the authors analyse the operation of thin-walled structures with complex open and closed cross sections. They offer a solution to the problem of non-linear stability of the investigated thin-walled structures using experimental and numerical methods [15][16][17][18][19][20].…”

The object of the research are short, thin-walled columns with an open top-hat cross section made of multilayer laminate. The walls of the investigated profiles are made of plate elements. The entire columns are subjected to uniform compression. A detailed analysis allowed us to determine critical forces and post-critical equilibrium paths. It is assumed that the columns are articulately supported on the edges forming their ends. The numerical investigation is performed by the finite element method. The study involves solving the problem of eigenvalue and the non-linear problem of stability of the structure. The numerical analysis is performed by the commercial simulation software ABAQUS®. The numerical results are then validated experimentally. In the discussed cases, it is assumed that the material operates within a linearly-elastic range, and the non-linearity of the FEM model is due to large displacements.

“…The high level of usability of thin-walled structures is associated with the elastic nature of the work. Thus, despite further work of the structure after reaching buckling, adverse effect on the correct operation is caused by the loss of stability which has been shown in studies [5,11,23,25].…”

“…The issues associated with stability, critical state and low post-critical state were considered for a long time, the results of which were shown in elaborations [3,5,9,12,16,17,23,25]. The axial compression is a process commonly found in exploitations of utility construction areas, aerial construction and automotive components.…”

The object of the study was a thin-walled profile with Z-shaped cross section made of the carbon-epoxy composite. The material model was prepared based on the implemented orthotropic properties. The purpose of the study was to determine the value of the critical load at which buckling occurs, the form of buckling and operating characteristics in critical condition. In order to achieve this numerical analysis were carried out. Additionally, the effects of the modification in arrangement of layers of the laminate to the stability and strength of thin-walled composite structures was presented. Numerical studies were carried out using commercial simulation software -ABAQUS®. Within the FEM research, both forms of buckling and the associated critical load, dependent on the configuration the layers of the composite were achieved. The analysis of the obtained results allowed the evaluation of the structure's work in relation to the level of energy consumption or rigidity estimation. In the paper only numerical simulations of the critical state were conducted.

“…The main problem with steel and composite structures is stability loss, an issue widely described in numerous research publications [1,2,5,6,8,15]. Despite the occurrence of buckling, compressive loads can still be carried by the tested structures, even after exceeding the post-critical condition.…”

The study investigates thin-walled steel elements in a form of openwork beams with holes described by variable geometrical parameters. The specimens are modeled numerically and additionally subjected to axial compression in order to examine the critical and post-critical behavior of the thin-walled profiles. The models of profiles are propped articulatedly on the edges of the cross-section in the upper and lower parts. The numerical analysis investigates only the problem of non-linear stability of these structures. The FEM analysis is stopped at the moment when the compressed profiles achieve the yield stress in order to determine their loss of stability without undesired strains. The numerical computations are performed using the ABAQUS ® program to investigate the impact of diameter variability in the thin-walled profiles with holes under allowable operational loads. The numerical investigation was performed only with respect to elastic work, ensuring the stability of thin-walled structures.
