霍普金森杆

霍普金森杆 一词源于英语 Hopkinson bar，只有国外的一些资料，你可以参照一下。最后你还可以参考Gray, George T.所著现收藏于美国洛杉矶国家图书馆一本叫《Classic Split-Hopkinson Pressure Bar Testing》的书

Split-Hopkinson pressure bar
The split-Hopkinson pressure bar is an apparatus for testing the dynamic stress-strain response of materials.

History
The split-Hopkinson pressure bar was first suggested by Bertram Hopkinson in 1914 as a way to measure stress pulse propagation in a metal bar. R.M. Davies and H. Kolsky refined Hopkinson's technique by using two Hopkinson bars in series, now known as the split-Hopkinson bar, to measure stress and strain. Later modifications have allowed for tensile, compression, and torsion testing.

Compression testing
For compression testing, two symmetrical bars are situated in series, with the sample in between. The first bar is the incident bar, which is struck by a striker bar during testing. The striker bar is fired from a gas gun. The second bar is the transmitte
