A discrete multi-layered explosion containment vessel (DMECV) consists of a thin cylindrical inner shell and helically cross-winding flat steel ribbons, which has advantages of convenient in fabrication and low in cost. The DMECVs generally fall into one of two categories: vessels designed for one-time-use and those for multiple-use. For a multiple-use DMECV, it is important to predict its remaining life under explosive loading for safe application. A method based on the growth of fatigue cracks in the inner shell is presented to predict the total number of explosive tests that a DMECV can withstand. By integrating the Paris law, an expression was obtained to calculate the crack growth in a single explosive. Then the expression was used as a recursion relationship to determine the new crack size for the next test, when the critical crack size is reached, the maximum number of explosive tests was obtained. Results are presented and discussed for an initial axial side-crack in the inner shell of the DMECV.
