Some creep problems taking into consideration finite deformations

Sukhorukov I.V.

The Institute of Hydrodynamics (Novosibirsk)

Simplest creep problems- 3-axes loading taking into consideration the changing of volume and without it for the Norton's law of steady creep are considered. The limitations of the validity of the geometry linear theory are established. The relaxation problem for a complex rod taking into account elastic deformations and damage is solved into geometry non-linear consideration. The quality distinction of the structure's behaviour is shown -into geometry non-linear consideration rupture takes place and into linear consideration it does not.
