Validity of Finite Element Method in Biaxial Buckling. Analysis of Laminated Composite Plates Subjected to In – Plane Loading

      Аннотация: To verify the accuracy of the present technique, buckling loads are evaluated and validated with other works available in the literature. Further comparisons were carried out and compared with the results obtained by the ANSYS package and experimental results. The good agreement with available data demonstrates the reliability of finite element method used. The aim of the present textbook was to verify the accuracy of the present technique (FEM) in biaxial buckling of composite laminated thin rectangular plates from the point of view of introduction and basic definitions; the formulation of mathematical modelling of rectangular laminates; the numerical method for predicting the buckling loads and shape modes of buckling of laminated rectangular plates; verifying the accuracy of convergence study; validation of the finite element method (FEM) program through comparisons with theoretical results, comparisons with the results of ANSYS Package, and comparisons with experimental results.
