“…The split Hopkinson pressure bar (SHPB) was originally developed in the 1940s for the measurement of the high‐rate flow stresses of ductile materials such as polymers and metals . Ductile materials can be tested this way under conditions of one‐dimensional stress (unconfined), but brittle materials such as glass are usually confined by a metal sleeve (Figure ) during dynamic deformation in an SHPB . The reason for using a sleeve is that brittle materials fracture before stress equilibrium is achieved.…”

“…Nie and co‐workers reported a double‐pulse SHPB technique (Figure ) where the duration of the first load can be controlled using a momentum trap positioned at various distances from a flange on the impact end of the incident bar (Figure ). This allows the damage state of the glass to be investigated at various points along the dynamic loading curve (Figure ).…”

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.

“…The method to simulate multiaxial compression was mainly through mechanical confining jackets. For example, Xu and Chen [1] studied the effects of loading rate, temperature, and damage effects on the compressive response of a borosilicate glass confined in sleeves of different materials. Chocron et al [2][3][4][5] investigated the effects of damage on the strength of a borosilicate (Borofloat 33 manufactured by Schott Glass) and a soda-lime glass (Starphire manufactured by PPG) under confinement.…”

Dynamic triaxial compression experiments were performed on borosilicate and soda-lime glass using a triaxial compression Kolsky bar that has two pressure chambers, one enclosing the specimen and the other enclosing the end of the transmission bar. A specimen is pre-stressed hydrostatically before being loaded by a dynamic axial stress wave. Specimen axial stress and strain are determined at high strain rates under a range of hydrostatic pressures. Borosilicate glass was subjected to pressures of 25, 50, and 100 MPa at a strain rate of 1500 s -1 , and soda-lime glass was subjected to 25, 50, and 75 MPa at 1100 s -1 . Dynamic results were compared to high-rate unconfined experiments, as well as low-rate confined experiments. It was observed that confined glass strength did not show clear strain-rate dependency. But confining pressure increased the glass strength.

This article details the implementation and application of the glass-specific computational constitutive model by Holmquist and Johnson (J Appl Mech 78:051003, 2011) to simulate the dynamic response of soda-lime glass under high rate and high pressure shock conditions. The predictive capabilities of this model are assessed through comparison of experimental data with numerical results from computations using the CTH shock physics code. The formulation of this glass model is reviewed in the context of its implementation within CTH. Using a variety of experimental data compiled from the open literature, a complete parameterization of the model describing the observed behavior of soda-lime glass is developed. Simulation results using the calibrated soda-lime glass model are compared to flyer plate and Taylor rod impact experimental data covering a range of impact and failure conditions spanning an order of magnitude in velocity and pressure. The complex behavior observed in the experimental testing is captured well in the computations, demonstrating the capability of the glass model within CTH.
