Experimental work conducted by D. B. Adolf has shown that a separable K-BKZ constitutive equation works reasonable well in predicting the stress relaxation observed in single step strain experiments for carbon black filled rubber. However, the memory requirements and numerical efficiency of the K-BKZ equation do not make it well suited for use in a production, three-dimensional finite element code. As an alternative, D. J. Segalman, K. Zuo, and D. Parsons have developed a "damage-like" constitutive equation which is computationally attractive. This formalism has been installed in the JAS3D finite element code. The requisite code inputs and numerical details of the constitutive integration are discussed, and solutions to selected problems are presented. Comparisons are made to data collected from both single and double step strain experiments.
