“…Figure shows the available experimental shock compression data for boron carbide of varying starting density as reported by different authors . Grady identifies three distinct regions in the hydrodynamic equation of state of boron carbide, each corresponding to the hydrodynamic compression of a particular phase: an ambient phase, a second phase that exists in the pressure range of 25–35 to 45–55 GPa, and a third phase beyond 45–55 GPa [Fig. (a)].…”

Boron carbide is characterized by a unique combination of properties that make it a material of choice for a wide range of engineering applications. Boron carbide is used in refractory applications due to its high melting point and thermal stability; it is used as abrasive powders and coatings due to its extreme abrasion resistance; it excels in ballistic performance due to its high hardness and low density; and it is commonly used in nuclear applications as neutron radiation absorbent. In addition, boron carbide is a high temperature semiconductor that can potentially be used for novel electronic applications. This paper provides a comprehensive review of the recent advances in understanding of structural and chemical variations in boron carbide and their influence on electronic, optical, vibrational, mechanical, and ballistic properties. Structural instability of boron carbide under high stresses associated with external loading and the nature of the resulting disordered phase are also discussed.

Dynamic wave interaction and crack propagation in glass have been observed with the edge-on impact (EOI) style test method using an exploding bridged wire (EBW) detonator. The existence of an interlayer or internal surface displayed meaningful wave distortions, delays, reflections, and decreasing amplitude. The interlayer materials used were rubber, stainless steel, and cut surface. The results indicate that the shocks passing the interlayer decrease following the impedance condition and that much of the crack is stopped at the interlayer. The damage pattern was analyzed with the energy and stress dissipation rate. *dkkim@kaist.ac.kr Fig. 8. Analysis of interlayered specimen.
