Abstract:
The method of characteristics was used to analyze the stress wave propagations in the brittle materials. The random nucleation and the growth of the cracks in the brittle materials were described by using the cohesive fracture model. A practical simu...

Abstract:
An experimental device with an explosive-driven flyer plate was designed for shock initiation of the explosives at elevated temperatures. This device can heat up the acceptor explosives uniformly and keep the donor explosives out of the heating. Base...
