Most reactions are thermally initiated, whether from direct heating or dissipation of energy from mechanical, shock, or electrical stimuli. For other than prompt shock initiation, the reaction must spread through porosity or over large surface area to become more violent than just rupturing any confinement. While burning rates are important, high-strain mechanical properties are nearly so, either by reducing existing porosity or generating additional surface area through fracture. In studies of deflagration-to-detonation transition (DDT), it has been shown that reaction violence is reduced if the binder is softened, either by raising the initial temperature or adding a solvent. In studies of cavity collapse in explosives, those with soft rubber binders will deform and undergo mild reaction whereas those with stiff binders will fracture and generate additional surface area for a violent event.
