Scaling Law for Criticality Conditions in Heterogeneous Energetic Materials under Shock Loading
A. Nassar, N. K. Rai, O. Sen +1
Initiation in heterogeneous energetic material (HEM) subjected to shock loading occurs due to the formation of hot spots. The criticality of the hot spots governs the initiation an…

Modeling meso-scale energy localization in shocked HMX, Part I: machine- learned surrogate model for effect of loading and void size
Anas Nassar, Nirmal K. Rai, Oishik Sen +1
This work presents the procedure for constructing a machine learned surrogate model for hotspot ignition and growth rates in pressed HMX materials. A Bayesian Kriging algorithm is…
