Earlier work has shown that the strength and growth of defects in elastomers is greatly affected by microstructure and mechanical constraint. Current work is focused on ionomeric materials which behave as elastomers under certain conditions of temperature, hydration, and mechanical constraint. These materials are typically characterized by large strains to failure. The present paper will deal with two aspects of their response that is important to design. The first is the creation of nonlinear constitutive equations that are appropriate for the description of their response in commercial codes. And the second is the development of strength concepts that are appropriate for the description of failure of such materials. Finally, the relationship of the material response and failure criteria to complexity of active stress states will be discussed.
