摘要/Abstract

摘要： 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.

关键词: principal resonance, visco-elastic system, multiple scale method, largest Liapunov exponent, bifurcation
