Effect of Explosion Bulge Test Parameters on the Measurement of Deformation Resistance for Steel

Abstract

This paper investigates the effects of varying some of the explosion bulge test conditions on assessment of the plate deformation resistance (bulge depth and plate thinning), focusing on four parameters: (a) use of cardboard wrapping to provide thermal insulation for the test plate prior to blasting (b) changing the means of supporting the charge above the plate from a cardboard box enclosure to a suspended stocking, (c) effect of testing temperature, and (d) the effect of crack starter weld beads on plate deformation. Of the four parameters, it was found that the use of a cardboard box enclosure provides measurably different outcomes compared to a charge suspended from the ceiling by a stocking.
