Effects of Confining Pressure on the Crack Growth Behavior in a Filled Elastomer Subjected to a Constant Strain Rate

Abstract

In this study the effects of different confining pressures and initial crack lengths on the crack growth behavior in a highly filled elastomer were investigated. The material under investigation contains hard particles embedded in a rubbery matrix. The specimens were strained at a constant strain rate of 16.67 in/in/min. Two confining pressures 500 psi and 1000 psi and two initial crack lengths 0.1 in. and 0.3 in. were considered. The experimental data were analyzed and the results are discussed.
