Advancements in Mechanical Raman Spectroscopy for applications in energetic materials

Abstract This paper aims to provide a detailed review of the fundamentals and applications of mechanical Raman spectroscopy in the field of energetic materials. Firstly, the principle behind mechanical Raman spectroscopy (MRS) is introduced to measure stress and temperature in a material. Afterward, the use of MRS to obtain microscale properties in an energetic material microstructure is discussed for quasi-static loading and dynamic loading experiments. Thereafter, the measurement of cohesive law parameters for interface separation in energetic material is explained. Finally, quantification of thermal conductivity at the interface level is presented. Later, the mechanism of obtaining time-resolved Raman spectra for the analysis of shock wave propagation in energetic material is explained. This work presents a comprehensive view of the existing applications of MRS as well as possible enhancements to the use of Raman spectroscopy to understand the behavior of complex energetic microstructures.
