| Abstract: | Experimental modeling of the dynamic fracture of a metal caused by a flyer plate of finite sizes revealed the formation of
a channel-like crack under the contact zone as a result of the focusing of side rarefaction waves. The system of coaxial cylindrical
cracks that sequentially form around the channel-like crack also has a spall nature of fracture and is localized at the sites
of interference of rarefaction waves. |
