An explicit, 2‐D, Lagrangian finite and discrete element technique is used to characterize thermo‐mechanical fluctuations in low pressure deformation waves propagating through particulate energetic solids. The technique combines conservation principles with a plane strain, thermoelastic‐viscoplastic and friction constitutive theory to describe deformation and motion of individual particles; interaction between particles is described using an energy consistent, penalty based contact method. Emphasis is placed on characterizing the relative importance of volumetric and surface dissipation as meso‐scale heating mechanisms. Predictions indicate that volumetric dissipation locally heats significant mass to modest temperatures, whereas surface dissipation locally heats a small fraction of mass to elevated temperatures that will likely trigger combustion. The dependence of hot‐spot mass fraction on friction coefficient is examined.
