Abstract

This article deals with the study of thermal stress distribution in a tube made of natural rubber/polyurethane material and subjected to internal pressure and mechanical load. From the obtained results, it is noticed that natural rubber material of the tube requires higher pressure to yield at the internal surface in comparison to tube made of polyurethane, for the initial yielding stage. Moreover, the tube of natural rubber material requires maximum hoop stress at the external surface as compared to the tube of polyurethane material. Values of the hoop/radial stress also increase with increasing temperature/mechanical loads in the contraction/extension region of the tube. The tube of natural rubber material is more comfortable than that of polyurethane.

Keywords: tube, load, stresses, pressure, temperature
