Modeling of Residual Stresses in a Polymer Cylinder Arising from Rotation and Cooling of the Starting Material

Abstract:

The determination of the stress-strain state of a polymer cylindrical body causes many difficulties. Due to the fact that the properties of polymers are dependent on a number of factors, including temperature. If there is a change in temperature along the radius during the manufacture of the product and production directly depends on dynamic loads, for example rotation, this factor can fundamentally change the distribution of stresses and strains in the thickness of the investigated structure. The body may develop significant residual stresses that reduce the operational quality of the product. Neglect of this factor can have a catastrophic effect on the reliability of the structure as a whole.
