Abstract Scope Polymer polyurea specimens were tested in tension at high strain rates (50 1/s to 3,000 1/s) using a split Hopkinson pressure bar. As polyurea is a weak material with very high strain to failure (over 100 %), special precautions had to be in place to insure reliable stresses and strains were measured while the specimen was in equilibrium. Unconventional to split Hopkinson pressure bar tests, high-speed digital image correlation was utilized to track a speckle pattern applied to the surface of each specimen to determine specimen equilibrium and measure strain during wave passes. Specimens at higher strain rates failed on the first wave pass, but those tested at lower strain rates did not. The mechanical strength of the polyurea was found to be increased over quasi-static tensile data. Results found help to improve the understanding of polyurea behavior under dynamic loading conditions.
