摘要

This paper presents uniaxial tensile loading tests on polyurea to analyze the characteristics of stress-strain behavior under a high strain rate. The results verify the process of stress-strain behavior, which shows the non-linear and rate-dependent process of stress-strain behavior, should be divided into several stages: a linear elastic stage, a non-linear transitional yielding stage and a hardening failure stage. Three different constitutive models are used to predict the behavior of material. By fitting the test datas and calculating the Root Mean Square Error (RMSE), the visco-hyperelastic model is more appropriate to represent the mechanical behavior of polyurea under high strain rate. It also shows the material would transform from a rubber-like material to a glassy-like material under strain rates of 600s -1 to 1500s -1.
