Fiber Bragg Grating Dynamic Sensing Through a Dispersive Spectrometer

Sensors
In the field of shock physics and energetic materials, Fiber Bragg Gratings (FBGs) are used to measure shock velocity, detonation velocity and shock pressure levels. They are also used to measure strain in structures loaded with explosive effects.

Deflagration to Detonation

, 1999
Thermonuclear explosions of Type Ia supernovae (SNIa) involve turbulent deflagrations, detonations, and possibly a deflagration-to-detonation transition. A phenomenological delayed detonation model of SNIa successfully explains many observational properties of SNIa including monochromatic light curves, spectra, brightness - decline and color - decline ...

Detonation: Should It Be Included in Hazard and Risk Assessment?

Chemical Engineering Transactions, 2016
The current practice in industry in vapour cloud explosions (VCE) assessment is to assume that all VCEs are deflagration. This practice has been in place for nearly three decades.

Enhanced damage mechanism of reinforced concrete targets impacted by reactive PELE: An analytical model and experimental validation

Defence Technology
Compared with PELE with inert fillings such as polyethylene and nylon, reactive PELE (RPELE) shows excellent damage effects when impacting concrete targets due to the filling deflagration reaction.

Region distribution of PTFE/Al-Ti composite jet and its penetration-deflagration damage mechanism for multi-spaced targets

Energetic Materials Frontiers
The reactive material-metal composite jet has received increasing attention due to the dual penetration-deflagration enhancement effect from high penetration of metal and deflagration reaction of Al and polytetrafluoretyhylene (PTFE) in the practical ...

Theory of magnetic deflagration

, 2007
Theory of magnetic deflagration (avalanches) in crystals of molecular magnets has been developed. The phenomenon resembles the burning of a chemical substance, with the Zeeman energy playing the role of the chemical energy. Non-destructive reversible character of magnetic deflagration, as well as the possibility to continuously tune the flammability of
