Opis:
The study includes considerations on the numerical methods of obtaining the correct forms of deformation of thin-walled plates subjected to pure shear, operating under conditions of critical loads. Selected methods were presented and subjected to comparative tests, allowing for the obtaining of a state of large deformations of a perfectly flat system, loaded in its plane. These methods are based on application various forms of initial imperfections into the system, either geometrically or physically. A new solution was proposed in this area, differing in its essence from most commonly used solutions.

Opis:
The study presents the results of comprehensive numerical analyses of an unusual solution in the field of geometry of holes in the wall of the wing torsion box subjected to torsion. Due to the nature of loads acting on the wing structure in flight conditions, it is possible to modify the current standard solutions. However, this involves a fundamental change in the nature of stress distribution and the resulting need to use new types of local reinforcements of the structure. The analyses were supposed to indicate the dependencies between the geometric parameters of the outcuts and the nature of advanced deformations and the distribution of internal forces.

Opis:
The paper presents an innovative concept of integral stiffening of the thin-walled structures based on the use of curvilinear elements. The analyzed system in the form of a thin-walled spatial structure was subjected to a non-linear numerical analysis, aimed at comparing the properties of the proposed solution with those of the reference stiffening. A comparative analysis of deformation forms and ranges as well as effective stress distributions was conducted. The tests constituted a preliminary analysis, aimed at determining the usability of the solution, which is the basis of the research process supported by an appropriate experiment.

Opis:
The paper presents results of research on thin-walled load-bearing structure model representing a fragment of plane wing torsion box. The basis for obtaining data on deformation character and stability loss process was a model experiment conducted using a dedicated experimental stand. On the basis of experiment results, adequate numerical simulations were conducted using software based on finite elements method. Results of non-linear numerical analyses allowed to determine the character of stress distribution and formulate conclusions regarding behaviour of the post-critical deformations of the examined wing part.

Opis:
This paper presents the results of experimental and numerical analysis in terms of the finite element method of plating components of aircraft load bearing structures. The subject matter of the study was composite panels with stiffeners in the form of a regular grid of oriented longitudinal elements in accordance with the directions of the principal stresses in the covering. The analysis was conducted in the buckling states of structural deformation which showed that structures with stiffeners exhibit much more favorable behavior in buckling deformation states than in laminar structures. This translates into stress distributions and their gradients, which are milder in forms of stiffened structures.
