Abstract In order to figure out the problems that FEM of HDPE is not easily stable with convergence and its constitutive model is relatively sophisticated, this paper conducted uniaxial tensile test and FEM to analyze the HDPE sheet. By comparing the results of tensile experiment and finite element simulation, it can be inferred that the non-linear Maxwell model was suitable for the situation under small deformation, but under large tensile deformation, the results of Maxwell model were quite different from expe-riments. However, the calculated results of Kwon model were consistent with experiment under both small tensile deformation and large deformation. Meanwhile, this paper also optimized the parameters of Kwon model. With the optimized parameters under 100 mm/min and 150 mm/min stretching rates, reference value could be reflected for the FEM of HDPE sheet under large deformation. Besides, analysis about the stress and strain in the sheet element indicated that the HDPE was under uniaxial tension, the stress and strain were not evenly distributed.The max stress and max strain located in the central area, which also explained the phenomenon that the sheet always broke in the middle.
