“…It was a small effect, but it was enough to alert them to the possibility that failure in shocked glass propagates some way behind a compressive shock. 319,320 These so-called 'failure waves' have been sought in ceramics, [321][322][323][324][325] although the evidence for their existence in materials apart from silica glasses is still controversial. 321,322 A few researchers have linked failure waves to resistance to hypervelocity impact.…”

“…Failure fronts have also been sought in other (opaque) brittle materials , although the evidence for their existence in materials apart from silica glasses is still controversial. Some researchers have claimed that in some brittle materials (such as alumina), failure does not propagate very far into the material from the impact surface , although others concluded this may be a measurement artefact .…”

The purpose of this review is to introduce the interested reader to the literature on the use of silica glasses in ballistic applications. These applications include optically transparent windows (where their amorphous nature, appropriate band gap, and cheapness make them ideal window materials) as well as layers in opaque armours designed to be resistant to shaped charges. In the latter application, their increase in volume (bulking) on fracture disrupts the shaped charge jet. Other topics covered in this review include low‐velocity damage by windborne debris, liquid and solid impact, dynamic methods of testing (Hopkinson pressure bar, Taylor impact, and plate impact shock loading), and constitutive models. The use of glass as a shaped charge is also discussed.

“…Without such enhancements, a ceramic model that is tuned to match one experiment often fails to predict the results in a different application. 2 The ceramic experiments of Hauver et al, 3 Lundberg and Lundberg, 4 Orphal and Franzen, 5 and Anderson et al 6 provide penetration rates and other time-varying target failure information. These time-resolved experiments are used to calibrate the damage model parameters (such as strain-to-failure or failure energy) that are associated with the progression of failure from its initiation to complete loss in strength.…”

Sphere impact experiments are used to calibrate and validate ceramic models that include statistical variability and/or scale effects in strength and toughness parameters. These dynamic experiments supplement traditional characterization experiments such as tension, triaxial compression, Brazilian, and plate impact, which are commonly used for ceramic model calibration. The fractured ceramic specimens are analyzed using sectioning, X‐ray computed tomography, microscopy, and other techniques. These experimental observations indicate that a predictive material model must incorporate a standard deviation in strength that varies with the nature of the loading. Methods of using the spherical indentation data to calibrate a statistical damage model are presented in which it is assumed that variability in strength is tied to microscale stress concentrations associated with microscale heterogeneity.
