Abstract

Abstract

An analytical method for the buckling discretely thin-wall stiffened composite curved panels under compression and shear is presented by use of finite strip-element method.In the report a simplified scheme for complex displacement functions is developed.It enables that computation to be performed in real number algebra easily.And a simple and easy way to satisify the boundary conditions is introduced.Numerical results are given and are in good agreement with available data.
