Abstract

In the constructions of multilayer cylindrical shells in heat-and-power engineering the materials, exhibiting rheological properties, such as concrete, polymers or fiber glass are widely used. In this connection, the study of temperature stresses in polymers, the analysis of the influence of various factors on the processes course under consideration, is of great importance. The paper presents an analytical solution of the thermal creep problem in polymers using the Kelvin-Voigt model for a rigidly clamped rod for various cases of temperature loading. The analysis of these solutions is also made on the example of a specific material for certain laws with changing temperature loads.
