摘要: The coupled electromagnetic (EM)-thermo-mechanical response of cyclotrimethylenetrinitramine-estane energetic aggregates under laser irradiation and high strain rate loads has been investigated for various aggregate sizes binder volume fractions. cyclotrimethylenetrinitramine (RDX) crystals are modeled with a dislocation density-based crystalline plasticity formulation the estane is finite viscoelasticity through nonlinear element approach that couples EM wave propagation heat absorption, thermal conduction, inelastic deformation. Material property local behavior mismatch at crystal-binder interfaces resulted in geometric scattering wave, electric field heating localization, stress gradients, density, shear slip accumulation. Viscous sliding was another energy dissipation mechanism reduced stresses thicker ligaments larger This investigation indicates complex interactions between waves mechanical behavior, accurate predictions heterogeneous materials.
