The destruction of homogeneous and composite barriers with metal-ceramic intermediate layers that interact with WNiFe-90 alloy impactors has been investigated. A comparison of the results for different types of barriers was provided based on the weight equivalence, i.e., the equality of weight per unit barrier area along the thickness. The initial impact velocity was in the range of 0.8–1.1 km/s. The registration of the process from the moment of strike of impactor to the formation of the developed fragmentation flow behind the barrier was carried out by a high-speed video camera. The displacement–time dependences for the characteristic planes of the target configuration, i.e., the rear end of the impactor and the rear surface of the barrier were plotted by processing video film. An analysis of these dependences allowed us to identify the features of barrier destruction. The strong difference in the geometry of the zones of destruction and the dynamics of the process for monolithic and composite barriers has been noted.
