Nonlinear Elasticity: experimental results and finite element modeling of hard neoprene elastomer failure

Failure in hard neoprene can be a very serious occurrence in industry. Since the material is resistant to oils, it is a popular choice for O-rings and hoses for use in fuel and oil lines. Notable elastomer failures include that of the Challenger space shuttle's O-rings and the (TM)Firestone ti...

Summary:Failure in hard neoprene can be a very serious occurrence in industry. Since the material is resistant to oils, it is a popular choice for O-rings and hoses for use in fuel and oil lines. Notable elastomer failures include that of the Challenger space shuttle's O-rings and the (TM)Firestone tires incident. Since elastomers are such a large part of daily life with a wide variety of uses, quantifying failure in these materials can mean the di erence between life and death, not just an inconvenient nuisance. It is desirable to not only determine the experimental failure properties of elastomer materials, but also to be able to use nite element analysis (FEA) to predict the behavior and failure of elastomers. In a world where engineering designs are becoming increasingly progressive and complex, engineers and scientists are relying more and more on FEA to predict the safety level of products. It is of utmost importance to ensure that the physical behavior of elastomers is successfully captured in FEA.
