Abstract
The paper presents approximate methods for the calculation of the stress distribution in a bollow cylinder of orthotropic viscoelastic composite materials under internal and external pressure. From the elastic solution the correspondence principe is appied to find the solution of associate elastic problem. Then three approximate methods: the collocation method, the direct method and the quasi-elastic method, are used to calculate the viscoelastic solution.
