Abstract

Abstract

In this work, we studied the compressive mechanical properties of polyethylene at different strain rates and obtained the stress-strain curves of polyethylene at different strain rates using static and dynamic experiments. We analyzed the stress-strain curves of polyethylene and discovered that the elastic modulus and the yield strength of polyethylene increase with the increase of the strain rate, and polyethylene has obvious viscoelasticity. The stress-strain curves have similar trends at different strain rates after polyethylene enters the plastic stage. We established a constitutive model of elastic zone, yield point and plastic zone according to compressive mechanical properties of polyethylene. The yield point and the plastic section of the model are in good agreement with the experimental results. As the elastic section adopts the linear elastic model, a certain deviation from the experimental results was observed, which can approximately describe the elastic behavior of the material.
