Abstract
Elastomeric polymers, like polyurea, are finding relevance in strengthening applications and as energy absorbing materials for structures and systems subjected to impulsive loadings. Understanding the dynamic behavior of these materials is essential for their application as an effective protective and retrofitting material. This paper presents the findings of a series of uniaxial tensile tests that were conducted on polyurea over the strain rate region from 0.006 to 388s-1. The stress-strain behavior of the polyurea sample was established at different strain rates, and key mechanical properties of the material were determined. The results indicate that the stress-strain behavior of the mater..
