Metal-polyurea composites have gained significant interest as a potential composite in resisting blast and ballistic impact loads. Although the loading mechanisms are different for these two types of loading, they both fall under the category of high-strain-inducing loads. Resisting such loads require high energy absorption capabilities, which is the main advantage that has promoted the use of elastomers such as polyurea in these applications. This chapter presents the findings of experimental and numerical investigations involving metal-polyurea composites under a blast load equivalent to 1kg of trinitrotoluene at a standoff distance of 150mm and a ballistic load of a projectile fired at an approximate velocity of 930m/s. The blast tests revealed that the steel plates with polyurea coating at the back face yielded lower residual deflection as well as minimum damage to the polyurea coating than the plates with coatings at the front face. It was also identified that an optimum coating t
