摘要：
A general one-dimensional geometrical non-linear model of a composite delaminated beam under arbitrary axial and transverse loading for any boundary conditions is derived for predicting the post-buckling behavior. The model comprises nonlinear equations based on the Von Karman kinematic approach, suitable for checking the effect of delamination and initial imperfection on the overall non-linear behavior. The differential equations, which incorporate the bendingstretching coupling effect, are solved by Newton's method using a finite-difference scheme. The delamination ratio parameter, bending stretching coupling and the initial imperfection are examined by means of parameteric analysis. © 1990.
