Abstract

This paper presents the results of tests on fully-clamped circular plates subjected to blast loading directed down a tube. Four series of tests were performed. In one set of experiments, the blast wave was allowed to progress unhindered down the tube to impinge upon the plate, and in the other tests, perforated plates were placed in the path of the blast wave to hinder progression down the tube, disrupting the blast and absorbing some of the kinetic energy. Results of the tests indicate that the perforated plates can be used as a form of passive mitigation.
