Title |
The dual approach to the evaluation of the load-carrying capacity of nonlinearly elastic bodies |

Abstract |
A variational problem associated with the limiting analysis of nonlinearly
elastic bodies the potentials of which linearly increase with the increase of
the modulus of the distortion tensor is considered. The limiting analysis dual
problem is formulated. The dual problem enables one to find a lower bound for
the limiting load - the magnitude of the external force beyond which
statically determinate deformed configurations stable with respect to finite
variations of the displacements do not exist.
By means of the finite-element approximation the limiting analysis
dual problem is reduced to the convex programming problem with linear
equality constraints. This problem is solved by the standard
conditional gradient method. The effectiveness of the approach proposed
is illustrated by examples. |
