Microballistics

Microballistics is a subfield of ballistics that investigates ballistic phenomena at micro- to mesoscale and over very short time intervals. It focuses on the microstructural and mechanical processes that occur when a high-velocity projectile interacts with material, such as a target or protective layer, and on how these processes influence outcomes such as penetration, fragmentation, and energy transfer.

Research employs high-speed diagnostics and imaging (high-speed photography, laser Doppler vibrometry), microstructural characterization (scanning electron microscopy, X-ray imaging, micro-CT), and computational tools such as finite element analysis, crystal plasticity, and molecular dynamics to model micro-scale damage and wave propagation.

Applications include armor and protective-material design, evaluation of ballistic performance, and fundamental materials science related to high strain-rate response. Microballistics helps explain how microstructural features—grain size, porosity, phase distribution—affect macroscopic outcomes like perforation, energy deposition, and fragmentation patterns.

The field intersects internal and external ballistics, impact mechanics, and materials science. Its development has been driven by advances in diagnostic instrumentation and computational modeling, enabling more accurate characterization of high-rate material behavior and improved protective technologies.
