The book consists of two parts. The first part is in fact a handbook giving a very detailed summary of the engineering models used for the analysis of high-speed penetration of rigid projectiles into concrete, metals and geological media. The second part of the book demonstrates the possibilities and efficiency of using approximate models for investigating traditional and nontraditional problems of penetration mechanics. The first class includes the traditional problems where a considerable progress has been achieved during the last years: analysis of the effect of spacing and layering on protective properties of plates and optimization of the multilayered shields; optimization of the shape of the projectiles penetrating into various shields; optimization of two-component ceramic-metal armor. The second class included non-traditional problems and approaches:...

The shield consists of adjacent plates manufactured from one of two possible materials, and the total thickness of the plates manufactured from every material is given. It is found that advancing any plate inside a shield

Hitherto, most blast in tunnel studies have worked to characterize blast profiles in smooth tunnels. This simplification effectively neglects wall effects including viscosity and shock reflections off the obstacles along the wall. The exploding wire technique, a rigorously confirmed method for producing accurate blast profiles, was used to simulate a blast event at the closed end of a scaled-down square tunnel with varying degrees of wall roughness. Results showed that the surface geometry of a tunnel's inner cross section has significant impact on the blast's pressure and impulse time histories. In particular, we found that wall roughness amplifies the maximum impulse in proximity to the blast source, contradicting the generally held belief that wall roughness primarily attenuates the blast wave impulse.
