Title:
Thermo-mechanical behavior of polyethylene under mechanical loads at cyogenic and elevated temperatures 
Abstract:
For the design of a polymer liner in a high-pressure vessel, experimental and numerical analyses of highdensity polyethylene (HDPE) are conducted under tensile and compressive loads. The effect of temperature on the mechanical behavior of the HDPE is investigated experimentally in a range of 223K to 373K. For tensile and compression tests, specimens are cut out of a prototype polymer liner, which is to be developed for automobile high-pressure hydrogen tanks. The specimens include manufactur...    »
