“…This creates the possibility of design plate elements with very favorable nonlinear-elastic characteristics, leading to a substantial increase the value of critical load and increase capacity of the structure. The issues of stability, critical behavior and limit load capacity of plate with holes are described, among others, in [5,9,15,18,19,21,24].…”

The subject of research is the numerical and experimental analysis of a thin-walled plate with the cut-out, made of the laminate and subjected to the axial compression. In order to ensure the stable plate work in the postcritical range, it need to force its work by higher flexural-torsional form of buckling. The scope of the research included nonlinear numerical analysis with Finite Element Method (FEM) and experimental verification of calculation results. For the composite material in numerical calculations, the model of orthotropic material in the flat state of tension was defined. For the mapping of the plate element coating finite elements of type SHELL was applied with a shape function of the second order to allow the mapping of the composite structure for the element thickness. The experimental research was carried out in a special grips providing the articulated support of the upper and lower edges of the plate. The deformation registration of compression structures were carried out with resistance extensometry. This allowed to define of postcritical equilibrium paths of real structure, showing the dependence of the force to displacement. The instrument used was a numerical program ABAQUS ® .

“…In some cases, the critical load can lead to the destruction of structure [1,26], then they are treated as a limit load. The exemplary papers dealing with local buckling of thin-walled structures are those written by Davis and Hancock [4,27], Graves-Smith [5] and Kumar [19]. The buckling of open section beams was the subject of the papers [3,8].…”

The subject of research is a rectangular plate with a cut-out subjected to regular compression. The plate articulately supported on the short side edges, made of a composite with high strength properties. The study concerned the numerical finite element analysis linear and nonlinear stability of the structure and the experimental validation of the results. The instrument used was a numerical program ABAQUS ® .

“…This can be done by making a notch in the centre of the plate and initiating the displacement in an opposite direction of the vertical stripes produced in the plate. Issues of stability, critical behavior, and limit load capacity of plates with holes are described, among others, in [8,12,17].…”
