EFFECTS OF THERMOMECHANICAL COUPLING IN A PLASTIC CYLINDER

The paper describes results from numerical experiments on the effects of thermomechanical coupling in a polypropylene homopolymer plastic cy linder of infinite length. The specimen is subjected to cyclic straini ng of fixed amplitude and cycle time. Thermal boundary conditions, in which convective heat loss only is considered, cover the full range of boundaries, from the ideally thermally insulated to the ideally conve ctive case. The temperature change distributions obtained from the mod el are in accordance with expected behaviour and are quanlitatively co nfirmed by preliminary industrial tests.
