Abstract
This study focuses on the fracture behavior of natural rubber under dynamic loading. Experiments were performed to determine the tear energy of rubber using trouser and pure shear specimens. The sample strain rates of the pure shear specimen were allowed to range from 0.01 to 311 s-1 by performing the tests with an MTS servo-hydraulic machine for sample strain rates 0.01 to 10 s-1 and a Charpy tensile impact apparatus for sample strain rates exceeding 10 s-1. Finite element analysis was used to define the pure shear region of the pure shear specimen. It was found that the tear energy varied with sample strain rates and specimen geometry and therefore, it may not be a proper parameter to predict the fracture of natural rubber. Finite element analysis of the fractured specimen indicated that comparing the strain energy density and the maximum principal stress at the crack tip to the toughness and tensile strength, respectively, may be more valuable in predicting crack initiation.
