Opis:
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.

Opis:
This paper reports the results of a numerical analysis of buckling in a carbon-fibre reinforced plastic (CFRP). The analysis involved determination of the first buckling mode and critical forces for the tested composite. The composite was tested for six different ply orientations. The analysis was performed on a closed section composite column. The objective of the analysis was to determine critical forces affecting the composite profiles with the applied ply orientations and, thus,to determine the laminate ply orientations which can carry the heaviest loads. The numerical modelling and all computations were performed using the Abaqus 6.14 software. In the analysis, we took account of boundary conditions and performed a discretization process in order to obtain correct results.

Opis:
The paper describes the process of symmetric bending of an aluminium specimen using two independent environments for numerical analysis. A FEM analysis is performed on an aluminium channel section. A comparison is made between the bending process performed in the Abaqus environment and that run with the Deform-3D system. In both numerical analysis systems, the crucial point is to determine the state of reduced stresses for a designed computer model. The paper provides a visual comparison of the profiles subjected to bending; it also determines displacements and stresses in the tested structures. To perform a nonlinear static analysis, we define a material model, determine boundary conditions, interactions as well as generate a mesh. The results produced with the two numerical systems agree to a very high extent.
