Abstract
The upper limit of the achievable constant strain rates in linearly elastic specimens loaded by a split Hopkinson pressure bar is estimated based on the specimen properties and a linear ramp loading. The criterion for a plateau of constant strain rate is derived and discussed. Dynamic experimental results on an S-2 glass/SC15 composite and polymethyl-methacrylate subjected to various ramp loadings verify the modeling results.
