Introduction and Literature Review on Buckling of Composite Laminates.

      Аннотация: Comprehensive literature reviews on buckling of composite laminated plates were presented and discussed thoroughly.Exact,analytical and semi-analytical solution techniques were compared and analyzed using different factors which include boundary conditions,plate dimensions and lamination scheme.Development of plate theories was considered in the analysis of buckling.It was found that there are two main theories of laminated plates which are known as linear and nonlinear theories.The two theories are depending on the magnitude of deformation resulting from loading the given plates.The difference between the two theories is that the deformations are small in the linear theory,whereas they are finite or large in the nonlinear theory.It was also found that higher order shear deformation theories can yield more accurate inter-laminate stresses and also avoids the need for shear correction displacement.In comparison between finite element method (FEM) and different numerical methods,it was found that FEM could be considered of acceptable accuracy,and could also be applied to different complicated geometries and shapes.
