| dc.description.abstract | A method for modeling the transient stress relaxation and creep behavior of acrylonitrile butadiene rubber has been developed. The behavior of the material is characterized through the use of transient stress relaxation and creep tests. The material exhibits viscoelastic properties. Since rubber can undergo large deformations the material is modeled using nonlinear viscoelastic techniques. In particular the material has been modeled using Schapery's correspondence principles. This is similar to traditional timetemperature superposition where changes in stress or strain compress or expand the time scale. Also a method has been developed and evaluated for interrelating the creep compliance and the relaxation modulus. Using stress relaxation and creep the nonlinear viscoelastic properties of acrylonitrile butadiene rubber will be modeled. The stress relaxation tests were also used as a method to model the interrelationship between relaxation modulus and creep compliance. In addition, to support the development of constitutive modes, dynamic mechanical tests were also used to determine if the material exhibited nonlinear viscoelastic behavior. | en |
