Abstract

Abstract

By making some assumptions, an analytical model was presented to analyze the compression process of the cylindrical metal tube subjected to an inward sliding detonation.And the corresponding numerical simulations were carried out to verify the analytical results.The analytical results agreed well with the numerical ones.So by fitting the analytical data, two expressions were obtained for the explosive thickness needed to close the tube and the tube closing time, respectively, in which involving different tube parameters such as tube inner diameter and wall thickness.
