“…The benefits brought by the TCs to this application can be understood by considering the properties that control the ballistic behavior of armor. This is a topic under debate, but here we adopt the views of Krell and Strassburger . They emphasize the influence of dynamic stiffness, hardness and, last but not least, the plate's fragmentation pattern.…”

Fifty years have elapsed from the moment the first light transmitting ceramic‐based commercial item—a sodium vapor‐based street lamp component—reached the market. This paper intends to be a brief chronicle (albeit not a chronology) of this first half century of translucent and transparent ceramic history. The main ceramic materials now available in a transparent state are presented and their main applications are described. Applications range from aerospace and relativistic optics to medical care, supermarket shopping, and modern warfare. Light transmitting ceramics usable as laser gain‐media, armor windows, IR domes, phosphors, scintillators, and electro‐optical components have been developed. The principal achievements this research produced are discussed. Processing strategies for full densification have been devised and quantitative relationships were established between different microstructural features such as amount and size distribution of porosity or level of birefringence, and the level of electromagnetic radiation attenuation they cause. Future prospects list ends the paper.

“…Strassburger et al also developed an experimental technique, which facilitated the visualization of damage propagation in a complex laminate target during projectile penetration [17]. A combination of high-speed imaging, photonic Doppler velocimetry and numerical simulations revealed a clear correlation between damage propagation, glass layer deformation and projectile position.…”

A systematic study has been performed to gather more detailed experimental information on the equation of state and the Hugoniot elastic limit (HEL) of soda-lime glass as well as the failure front phenomenon. The key innovations of this study comprise experimental as well as analytical aspects. On the one hand, an extensive planar plate impact (PPI) test series has been carried out over a wide range of shock loading stress levels instrumented with two high-speed cameras and laser interferometers (PDV and VISAR). On the other hand, a systematic analysis concept has been developed and evaluated, including a combination of Lagrange diagrams with velocity profile data and a derivation of the equation of state together with an error estimation. Impact velocities ranged from 500 to 3000 m/s resulting in loadings of the soda-lime glass targets between 3.5 and 20.8 GPa. For stress levels between 3.5 and 6.7 GPa two high-speed cameras with 5 Mfps, positioned at the side and rear of the specimens, enabled the observation of shock waves and two different kinds of failure fronts. Therefore, visual information could be gathered not only in the purely elastic regime, but also in the transition region above 4 GPa and at stress levels beyond the HEL. The HEL of the soda-lime glass is determined to $$\left(5.0 \pm 0.2\right) \mathrm{GPa}$$ 5.0 ± 0.2 GPa . For the onset of an internal failure front a minimum longitudinal stress between 3.8 and 3.9 GPa is identified. The evaluated failure front velocities range from 800 to 2100 m/s. From the observed release response a minimum spall strength of 6.7 GPa and release wave velocities between 5740 and 9500 m/s are deduced.

Stronger glass products: Lessons learned and yet to be learned

Potential for obtaining stronger glass products is discussed. Flaws, mostly forming‐ and handling‐generated and accelerated crack growth due to surrounding environment appear to give a strength distribution which is usually a factor of 500‐1000 less than the estimated theoretical strength. Contrary to traditional teachings emphasizing glass strength to be an extrinsic behavior, it is suggested that the atomic network topology determines the shear and hydrostatic yield strengths which are a precursor to the nucleation and growth of network cavitation, in turn, leading to generation of flaws and stress‐assisted growth starting from glass product‐forming processes. Hence, for stronger glass products, research is needed to develop fundamental understanding of the interrelationship between network topology, yield strengths, flaw cavitation and growth in molten glass as well as in solid glass as a function of glass composition and the complex stress fields around indents and impacts.
