| Abstract: | Thermal infrared radiation (TIR) detection tests of ultra-high molecular weight polyethylene (UHMWPE) were conducted subjected to uniaxial tension at four kinds of loading speed, 5 mm/min, 50 mm/min, 100 mm/min and 500mm/min. The relationships were analyzed between tensile stress and strain, average infrared temperature (AIRT) and strain, and AIRT and mechanical work. The testing results showes that, AIRT depended on the tensile strain and the tension speed positively. At the initial stage of tension, the AIRT of UHMWPE specimens decreased at first, and then increased. The AIRT increased with mechanical work until break. |
