Abstract
This study presents the verification of computational models for the analysis of biaxial buckling in plates. The verification was performed by comparing the numerical results obtained in this study with results found in scientific references published by other authors. The computational models were developed in the ANSYS® software, which is based on the Finite Element Method (FEM), and the SHELL 281 element is used. The mesh convergence tests demonstrate the convergent behavior of the simulations performed for the analyzed examples, which are: a square plate under biaxial elastic buckling, and a rectangular plate with stiffeners under biaxial elasto-plastic buckling. From the converged mesh, maximum differences of 0.84% and 3.89% were achieved when compared with references, respectively, for the elastic and elasto-plastic biaxial buckling. These results indicate that the proposed computational models were adequately verified.
