Influence of Sample Geometry on Sweeping-Detonation-Wave Spallation in Tantalum
TL;DR: In this article, sweeping-wave loading of a 10 cm radius curved Ta plate is observed to lead to an increase in the shear stress as a function of increasing obliquity, and display a more developed level of damage evolution, extensive voids and coalescence.

TL;DR: In this paper, a physically-informed continuum crystal plasticity model is presented to elucidate the deformation mechanisms and dislocation evolution in body-centered-cubic (bcc) tantalum widely used as a key structural material for mechanical and thermal extremes.

The Shock Hugoniot of the Intermetallic Compound, Ni3Al
TL;DR: The behavior of the intermetallic compound, Ni3Al under shock loading conditions has been measured in this article, where the Hugoniot Elastic Limit occurs at ca. 530 MPa, which converts to a 1-D yield stress of 273 MPa.

Damage in Low Alloy Steel Produced by Sweeping, Interacting Detonation Waves
TL;DR: In this article, the authors investigate damage generated in AISI 4130 steel by the combined effects of oblique drive and interacting detonation waves and show that the damage is correlated with the velocimetry data.
