The interrelationship study reveals that irrespective of the nature of stimuli, explosion is the final event and occurs due to a thermal mechanism. This study shows that under severe impact thermal stimuli can occur. If the thermal stimuli are equal to or greater than the activation energy of the composition then ignition of the flash composition will occur.<\/p>\n<p align=\"left\"><strong>Keywords:<\/strong> flash composition, fireworks, mechanical and thermal sensitiveness, correlation analysis<\/p>\n<hr \/>\n<p><em><strong>Ref:<\/strong> JPyro, Issue 23, 2006,&nbsp;pp51-60<br \/> <\/em><em>(J23_51)<\/em><\/p>\n","protected":false},"excerpt":{"rendered":"<p>S.
