Study of the Elastic Constants and Related Properties of β-HMX by Brillouin Scattering (CAT#: STEM-ST-0110-YJL)

Introduction

The structure-function relationship for many materials remains a fundamental question in solid-state research. Concomitant with a broader understanding of this relationship, the properties of solid-state materials are becoming increasingly tunable. This comprehension, particularly for the mechanical properties, is essential to the development of secondary explosives, such as HMX scyclotetramethylenetetranitramined, that characteristically balance low sensitivity to detonation with high power. Elasticity is fundamental to understanding such materials' mechanical response to stress. The elastic constants, which arise from intermolecular forces, provide a window into the microscopic interactions that affect phonon propagation, lattice compressibility, and thermal conductivity.
