“…In this case we have a situation analogous to the decrease of the material strength at high temperatures. For example, the recent spall fracture experiments with aluminum and magnesium showed precipitous drop in the spall strength of preheated samples as temperatures approached the melting point [13]. From the mesoscale point of view, high dispersion decreases the material density; the material became more porous and less stable.…”

“…In particular, the plate impact experiments [4] with ductile steels show that the maximum spall strength corresponds to the tests with the maximum mesoparticle velocity dispersion; spall fracture experiments with aluminum and magnesium show drop in the spall strength as the temperature (dispersion) approached the melting point [13]; the impact experiments and the microstructure investigation [4,12] show that the mesoparticle velocity dispersion is strongly connected with the intensity of relaxation processes.…”

“…Examination of the spall behaviour of various magnesium alloys has been of interest to a number of researchers [52,53]-particularly at elevated temperatures [48,54,55]. Schmidt et al [56] measured the spall strength of AZ31B-H24 and reported a value of 1.5 GPa for the onset of incipient spall at room temperature.…”

Magnesium, titanium and zirconium and their alloys are extensively used in industrial and military applications where they would be subjected to extreme environments of high stress and strain-rate loading. Their hexagonal close-packed (HCP) crystal lattice structures present interesting challenges for optimizing their mechanical response under such loading conditions. In this paper, we review how these materials respond to shock loading via plate-impact experiments. We also discuss the relationship between a heterogeneous and anisotropic microstructure, typical of HCP materials, and the directional dependency of the elastic limit and, in some cases, the strength prior to failure.

“…Modern, high-resolution methods for monitoring the stress and particle velocity histories in shock waves and equipment have been created (e.g., Barker and Hollenbach [42]; Kanel [43]; Kanel et al [44]; Millett and Bourne [45]; Bourne and Stevens [46]; Bourne [47]; Gu and Ravichandran [48]); numerous investigations into the mechanical properties of different classes of materials have been undertaken (e.g., Meyers [6]; Gu and Ravichandran [48]; Steinberg [49]; Johnson et al [50]; Kanel et al [51]; Millett et al [52]; Lopatnikov et al [53]; Zaretsky et al [54]; Gebbeken et al [55]; Bronkhorst et al [56]), and numerous phenomenological as well as microscopic models have been developed (e.g., Wallace [57]; Swegle and Grady [58]; Steinberg [49]; Meyers [6]; Kanel et al [59]; Nellis et al [60]; Bourne and Gray III [61]; Krüger et al [62]; Chijioke et al [63]; Boidin et al [64]; Petit and Dequiedt [65]). However, in spite of a perfectly adequate general understanding, experimental methodology, and theory, material models do not agree in detail, especially for anisotropic materials.…”

Studies of anisotropic materials and the discovery of various novel and unexpected phenomena under shock loading has contributed significantly to our understanding of the behavior of condensed matter. The variety of experimental studies for isotropic materials displays systematic patterns, giving basic insights into the underlying physics of anisotropic shock-wave modeling. There are many similarities and significant differences in the phenomena observed for isotropic and anisotropic materials under shock-wave loading. Despite this, the anisotropic constitutive equations must represent, mathematically and physically, the generalization of the conventional constitutive equations for isotropic material and reduce to the conventional constitutive equations in the limit of isotropy. This report presents the current state of the art in the experimental and theoretical developments of this fascinating field.
