Abstract

A typical cylindrical explosion device scaled down from actual Fuel-Air-Explosive Devices is selected as the research object of this paper, The behaviors and properties of material at high strain rates are studied, an electrical measurement is designed and carried out in the explosion chamber, the dynamic strain history of the large-deformation shell is measured and crucial fracture parameters are obtained. At the same time, the fundamental principle of the method is given, and the experimental results are discussed in detail. Some data are compared with theoretical solutions and they coincide well with each other.
