About the redistribution of stress in a orthotropic viscoelastic plate in the vicinity of round enclosure

The balance of a orthotropic viscoelastic plate in the vicinity of round enclosure under the influence constant stretching forces is considered. The task is examined in the network of the anisotropic viscoelasticity linear theory with various hypotheses of the account of viscoelastic properties of material and various variants of enclosures. A great difference in the results while using this or that hypothesis was shown. The presence of great redistributions of stress near the edge of enclosures was given.
