heal.abstract	The stability and post-buckling response of simple perfect and imperfect systems made of nonlinear elastic material are thoroughly discussed. The perfect systems correspond to the three types of bifurcation points, i.e. stable symmetric, unstable symmetric and asymmetric. Material-dependent stability conditions are properly established. It is found that the mechanism of buckling of perfect systems associated with a stable symmetric bifurcation point may become unstable depending on the value of the material nonlinearity parameter. Moreover, it is established that the effect of compressibility on the buckling load may be considerable in case of imperfect systems which in their ideal state are associated with an asymmetric bifurcation point. © 1989 Springer-Verlag.	en
