| 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 the no nlinear numerical analysis with Finite Element Method (FEM) andexperimental verification of calculation results. For the composite material in numerical calculations, was defined the model of orthotropic material in the flat state of tension. For the mapping of the plate element was applied coating finite elements of type SHELL with shape function of the second order to allowing the mapping of the composite structure for the element thickness. The experimental research was carried out in a special grips pr oviding the articulated support of the upper and lower edges of the plate. The deformation registratio n ofcompression structures were carried out with resistance extensometry. Thisallowed to define ofpostcritical equilibrium paths of real structure, showing the dependence of the force to displacement. The instrument used was a numerical program ABAQUS ® . |
