摘要：

The stability of the homogeneous deformation for an elastic bar subject to uniaxial tension is studied. It is shown that the critical extension at which the homogeneous deformation becomes unstable is a decreasing function of the aspect ratio. Furthermore, it is shown that for small aspect ratios, the homogeneous deformation need not be the global minimizer of the total energy, even though it may be a local minimizer. © 1990 Kluwer Academic Publishers.
