Elastoplastic behavior of marble, granite, and quartzite under shock compression

Theoretical Calculation Method for the Hugoniot Elastic Limit of Hard Rock Based on Ideal Elastoplastic Model

“…As reported by Ahrens et al [1] and Kovalev et al [4], amplitude decreasing of the elastic precursor is found in plate impact experiments for rock-like novaculite, quartzite, marble, and granite.…”

“…In this study, we shall make some corrections as shown in Figure 8(b). Firstly, a diffuse and smooth front of the elastic precursor as observed by Kovalev et al [4] and Li et al [7] should be considered. Secondly, the damage front cannot overtake the leading-edge of the elastic precursor, but the damage zone and the elastic precursor partly overlap near the inflection point of the wave front.…”

“…e Hugoniot elastic limit (or HEL, for short) is a fundamental dynamic material property of solid materials, and it is important to study stress wave propagation and evolution of internal damage of materials under explosion and high velocity impact effects [1][2][3][4][5]. e HEL is believed to represent the maximum stress that a rock or other solid materials can withstand under conditions of rapid onedimensional compression without internal rearrangement taking place in the material at the shock front.…”

Plate impact experiments to investigate shock-induced inelasticity in Westerly granite

“…Shock-induced properties of geological materials have been investigated using a variety of techniques including explosive detonation loading, impact cratering experiments, and flyer-plate impact studies. For example, Kovalev et al [10] used explosive loading along with manganin pressure gages to investigate elastoplastic shock-wave profiles in marble, quartzite and granite. They found the shock-wave front to split into a leading elastic precursor followed by a plastic (in-elastic) compressive wave; the amplitude of the elastic precursor is observed to decrease with increasing propagation distance in the samples.…”
