| Abstract: | The stress problem in an infinite cylinder of temperature-dependent material properties may be treated by a quasi-linear approach based on radial subdivision and time step-wise integration. The temperature field during cooling is obtained as a multi-region eigenfunction series, while the stresses are obtained from the integration of the equilibrium displacement equation by taking into consideration thermoviscoelastic deformations. The particular case of a two-region formulation and its solutions are described in full. Numerical examples of induced stress predictions in optical glass fiber are given. |
