Abstract:
Dynamic mechanical behavior of metallic materials under complicated loading conditions has attracted much attention. However, it is hard to obtain the dynamic Bauschinger effect of metallic materials due to the limitation of loading equipment. In ord...

Abstract:
In order to study the impact of the metal jet formed by a shaped charge on a solid-rocket engine, the shaped-charge blasting experiment was carried out, and the jet impingement experiment was performed for the shaped jet impacting a certain-size engi...

Abstract:
The photomultiplier tube (PMT) is the core component of the neutrino detector. It is a thin shell structure made of glass material with a vacuum inside and arranged to work in deep water. Once the PMT is crushed, it generates a strong shock wave, whi...
