高密度聚乙烯单轴拉伸力学性能试验研究
The mechanism property analysis of the uniaxial tensile experimental about the high density polyethylene
摘要
Abstract
Since the high density polyethylene (HDPE)is popularly used in areas such as the chemis-try,construction and the military project,the types and the conditions for usage are verified.The uniaxi-al tensile test on the smooth surface specimens and the pattern surface specimens is performed,with dif-ferent stretching speed and tensile directions.The experiment shows that the yield platform value of the smooth specimens also increases with the increase of the stretching speed,which is under the transversal tension.When the stretching speed is 150 mm/min,the smooth transversal tensile specimen has incon-spicuous second yield point,which means that it has better performance on the tension.The rate depend-ence of the pattern specimens is more obvious and its value is 5.02%under 3 different stretching speed. However,the load the pattern specimens can undertake is lower contrast with the smooth specimens.It is easier for the pattern specimens to be broken than the smooth specimens,and it is also easier for the lon-gitudinal tensile specimens to be broken than the transversal tensile specimens.Consequently,the smooth transversal tensile specimen has better tensile strength.关键词
