Rovinný problém ztráty stability v tahu
The stability of a parallelepiped subjected to finite stretching is investigated. The materials is assumed to be elastic an orthotropic, with arbitrary non-linear physical properties. The deformation is divided into two parts: a finite initial deformation and a small additional deformation. All the relations which correspod to the additional deformation are linearized. After expanding the additional displacements into series, an ordinary differential equation with corresponding boundary conditions...
