Abstract

A typical cylindrical explosion device is selected as the test object, which is scaled down with the actual Fuel-Air-Explosive device. The behaviors and properties of material at large deformation and high strain rate are referred. An electrical measurement is carried out in an explosion chamber. The dynamic strain history of the expanding shell is measured. The crucial fracture parameters have been obtained. The fundamental principle and specific test method are given, and the results are discussed in detail in the paper. Some data are compared with theoretical solutions and they tally well with each other.
