摘要: A micromechanics-based model is developed to predict the effective thermo-mechanical properties of energetic materials, which are composite materials made from agglomeration particles a range sizes. random packing algorithm implemented construct representative volume element for heterogeneous material based on experimentally determined particle diameter distribution. The mechanical then evaluated through finite modeling, while its thermal approach. first carefully validated against results literature and used estimate particular materials. Good agreement found between experimental predictions. stress-bridging phenomenon in particulate captured by model. Thermodynamic averaging shown be poor representation estimation these
