Research Abstract
This study proposed an ultra-thin and -light blast mitigation panel and a blast resistant design of structures against the close-in explosion in which an explosion occur at relatively close distance to a structure. An aluminum honeycomb panel was selected as a mitigation system, and a series of close-in explosion tests were conducted by using Composition C-4 high explosive. In the explosive tests, the effects of the aluminum honeycomb on the response of a steel plates behind the aluminum honeycomb panel was investigated. The test results revealed that the aluminum honeycomb panel exhibited high blast mitigation effects. A single degree of freedom model considering the mitigation effect was proposed.
