Special Issue Information

Dear Colleagues,

Energetic materials are the energy sources for rocket motors, missile, and cannon, etc. In recent decades, astronautics has developed so fast and many innovations on energetic materials have bloomed, which promotes the to the further exploration of unknown space.

Energetic materials must be capable of maintaining structural integrity over a demanding range of operating and storage conditions. Significant mechanical loads are introduced in the conditions, especially for case bonded grains. The strain capability of energetic materials at a low temperature under either very low strain rates for cooldown of the motors under low-temperature storage or high strain rates due to combustion pressurization of a cold motor are concerned. For instance, the solid propellants must possess high enough moduli to avoid excessive deformation under high-temperature combustion conditions and high enough creep under long-term exposure to high temperatures. Additionally, the solid propellants must possess enough toughness to resist fracture or fragmentation upon failure under high stress or strain rates. Such fragmentation yields high surface area, which can produce an explosive reaction given an combustion source and the confinement of the rocket motor case.

Modern techniques, such as non-destructive inspections, mechanical tests in laboratory, analytical solutions, and multi-scale numerical simulations have been excessively employed onto exploring the properties of energetic materials during pouring, curing, storage, and combustion recently. Such valuable theories and practices are worthy of broadcasting and hopefully the energetic materials area can go forward a small step.

In this topic, there is a focus on the fundamental problems of energetic materials during its pouring, curing, storage, and combustion. Both theoretical and experimental contributions can be submitted.

It is our pleasure to invite you to submit a manuscript to this Special Issue, including full papers, reviews, and short communications.

Investigating the constitutive relationship and the damage failure mechanism of solid propellants is of significance for improving the safety, storage period and use efficiency of solid rocket motors. This paper focuses on the complex mechanical response behavior of composite solid propellants under loads and introduces experimental research on quasi-static and dynamic mechanical properties. Limited by the accuracy of instruments and testing methods, the research progress of macroscopic constitutive models, mesoscopic mechanical models and microscopic molecular models is summarized from the perspective of numerical simulations based on model scale and modeling methods. This paper tracks the historical progress of key models and summarizes the main achievements and prospects in this field. The research in this paper has high scientific and theoretical significance and engineering application value. It can provide an important reference and guidance for the structural optimization and performance improvement of solid propellants and lay a solid foundation for the development of solid rocket motors.
