Spallation occurs when two rarefaction waves interact in a body and produce enough tension to fracture it. The principal content of investigations of spall phenomena that have been conducted are: (i) metallographic examination of the spall zone in recovered samples to obtain the correlation of the degree of damage with various features of the stress history [1-3] and (ii) instrumental measurement of resistance to dynamic fracture [4][5][6]. In the former case the result is information about the ability of the material to withstand shock loading, about the mechanism of nucleation and development of micro-cracks or pores, and statistical description of these processes. Dynamic measurements (free-surface velocity profiles or pressure on the interface with a soft material) during the shock-wave loading give the most correct data about stresses present during the spall process. The theoretical background of these measurements is discussed in Section 1.2 of this chapter.The damage rate, which is approximately equal to the product of concentration of damage nucleation sites and the average growth rate of damage at the sites, cannot be arbitrarily large. Under conditions of rapid dynamic loading, fracture is an essentially rate-dependent process. As a result, the spall strength value is not a material constant. It is more correct to speak about the resistance to fracture as a function of strain rate and other parameters of state. Since the fracture evolves over a period of time comparable with the duration of a shock wave experiment, we have to identify the stage of fracture which corresponds to the fracturing stress as this stress is determined by dynamic measurements. The acoustic analysis of spallation in relaxing media presented in Section 1.3 shows a correlation among the initial damage rate, the unloading rate in the incident shock pulse, and the freesurface velocity profile that is measured. Using this analysis, the initial damage rate can be estimated directly from the free-surface velocity profile.The typical behavior of materials of different classes-metals and alloys, brittle single crystals and glasses, and elastomers-is described in Section 1.4. A series of additional factors can influence the fracture process that

“…Since the failure wave was first observed propagating in K19 glass under impulsive loading below its Hugoniot Elastic Limit (HEL or σ HEL ) [1] , a series of plate impact experiments, bar impact experiments and impact soft recovery experiments have been conducted on a range of glasses under various impact stresses traced by embedded manganin stress gauge [2,3] or strain gauge [4,5] , velocity interferometer system for any reflector (VISAR) [1,2,6,7] and high-speed photography [8,9] . The formation and propagation of the failure wave were confirmed further in impacted glass plates and bars with an analysis of their shear strength and spall strength.…”

The failure wave has been observed propagating in glass under impact loading since 1991. It is a continuous fracture zone which may be associated with the damage accumulation process during the propagation of shock waves. A progressive fracture model was proposed to describe the failure wave formation and propagation in shocked glass considering its heterogeneous meso-structures. The original and nucleated microcracks will expand along the pores and other defects with concomitant dilation when shock loading is below the Hugoniot Elastic Limit. The governing equation of the failure wave is characterized by inelastic bulk strain with material damage and fracture. And the inelastic bulk strain consists of dilatant strain from nucleation and expansion of microcracks and condensed strain from the collapse of the original pores. Numerical simulation of the free surface velocity was performed and found in good agreement with planar impact experiments on K9 glass at China Academy of Engineering Physics. And the longitudinal, lateral and shear stress histories upon the arrival of the failure wave were predicted, which present the diminished shear strength and lost spall strength in the failed layer.KEY WORDS the failure wave, progressive fracture model, glass, planar impact

“…In experiments described by Razorenov et al (1991) and Kanel et al (1992), the shock pulse was introduced into the glass sample through a copper baseplate. When the peak stress of the shock pulse was far below the elastic limit, a short negative velocity pullback appeared in the free-surface velocity profile as a result of the re-reflection of the rarefaction wave at the sample-baseplate interface.…”

“…This effect has been shown to be reduced by lowering temperature (Dremin et al, 1992). Rasorenov et al (1991) were the first to observe the phenomenon of delayed failure behind the elastic wave in glass, across a front which has been called a fracture or more lately a failure wave. Such a wave was proposed by Nickolaevskii (1981) who used the concept of a wave of fracture passing through a brittle material to explain the elastic limit.…”
