“…12 and 13͒ and spall strengths ͑over 4 GPa͒ resulting from their amorphous silicate network structure. 14 This structure also gives rise to the possibility of densification during compression and this manifests itself in leading ramps on the rising edge of the wave. 15 The highly filled glasses, on the other hand, exhibit fast rising elastic waves and have similar wave profiles to those of polycrystalline ceramics.…”

Articles you may be interested inAcoustic emission analysis on tensile failure of steam-side oxide scales formed on T22 alloy superheater tubesThe compressive failure of soda-lime glass under uniaxial shock loading has been the subject of much recent discussion. Evidence of failure occurring behind a traveling boundary that follows a shock front has been accumulated and verified in several laboratories. Such a boundary has been called a failure wave. The variations in material properties across this front include complete loss of tensile strength, reduction in shear strength, lowered acoustic impedance and sound speed, and opacity to light. It in many ways resembles a phase boundary. While these observations are generally held to be true, there is no universally agreed mechanism for the process or processes that gives rise to the failure. It is the object of this work to present the results of plate impact experiments that aim to identify the mechanism by which the failure wave propagates. The experiments indicate that the failure is nucleated by the shock wave at surfaces, and that deliberately introducing flaws by roughening the surface speeds the fracture of the material leading to a failure wave close to the shock front.

“…14 The distinguishing feature of such a wave is the loss of tensile strength across the front and the reduction of shear strength that is also observed. [15][16][17] Since the initial observation of these waves, high-speed photography has revealed their form as a front resembling propagating fracture following some distance behind the shock. 18,19 Some authors have claimed that the wave travels at constant speed while others have contended that it slows as it moves in from the impact surface.…”

Influence of temperature on the electrical conductivity of glass under shock effect AIP Conf.Isothermal and shock compression of high density ammonium nitrate and ammonium perchlorate AIP Conf.One of the outstanding questions concerning the compressive behavior of brittle materials concerns the failure wave observed in glasses. While much work has centered around relatively open structure, low density glasses such as borosilicate ͑pyrex͒ and soda-lime ͑float, which is partially filled͒, none has addressed the response of highly filled lead glasses. This work presents the results of a series of plate impact experiments carried out on the lead glass DEDF.™ This material was shocked in uniaxial strain and the longitudinal and lateral components of stress and strain were measured. The failure wave, observed in lower density glasses, was observed in this material but its velocity reached that of the shock at less than twice the Hugoniot elastic limit ͑HEL͒.

“…The values of the HEL for soda lime glass obtained from various sources ͑Table I͒ range from 3-6.4 GPa. [7][8][9]11 Of these studies, only Resseguier, Cottet, and Migault 7 determine value of the HEL based on reversible compression of soda lime glass. They report the value of the HEL as 3 GPa.…”
