“…A micro-scale level of deformation analysis can be recorded using DIC [77]. Rae et al [79] have applied the DIC technique to determine microscopic displacement and strain fields of PBX during Brazilian disc test. Zhou [81] used DIC to calculate strain fields and analyze micro-scale deformation and fracture behavior of a PBX simulant under tensile stress.…”

Simulant polymer bonded explosives are widely used to simulate the mechanical response of real energetic materials. In this paper, the fracture resistance of a simulant polymer bonded explosive (PBX) is experimentally investigated. The simulant is composed of 80 wt.% soda lime glass beads (SLGB) and 20 wt.% high impact Polystyrene 825 (HIPS). Brazilian disk tests are performed to characterize the tensile and compressive properties. Fracture toughness and energy tests are performed in the semi-circular bending (SCB) configuration on 80, 81, 82, and 83 wt% SLGB compositions. Digital image correlation is performed to record the surface displacements and calculate surface strains during testing. The micromechanical behavior of ductile and brittle fracture are evaluated using digital microscopy and scanning electron microscopy of the fracture surface. It is determined that (i) the manufacturing process produces a credible simulant of PBX properties, and (ii) the SCB test measures fracture resistance with a reasonable coefficient of variation. 4 ACKNOWLEDGMENTS This project is supported by Sandia National Laboratories. We are truly thankful to Michael J. Kaneshige for his unconditional support during this time period. We would also like to express our gratitude to him for providing insight, knowledge, and expertise that assisted the research greatly. His comments on our newly developed novel method of manufacturing mock energetic materials, mechanical testing methods, and digital image correlation technique helped us to understand the sources of uncertainty in our experiments.

To determine the influence of temperature and strain rate on the mechanical behavior of JOXL‐1 explosive, the stress‐strain curves of JOXL‐1 explosive at different temperatures (233 K‐473 K) and different strain rates (110 s−1‐400 s−1) were measured using a split Hopkinson pressure bar (SHPB) experimental system with a temperature control device. The results show that the dynamic mechanical properties of this explosive are sensitive to the strain rate and temperature in the experimental temperature range. The failure stress increases with increasing strain rate and decreases with increasing temperature. The failure strain increases with increasing strain rate, but it is almost unaffected by temperature. The DSC analysis shows that the JOXL‐1 explosive has good thermal stability when the temperature is lower than 391.37 K and that binders in the explosive gradually decompose when the temperature is higher than 391.37 K.
