Messung und Simulation von stationären Stoßwellen in Armco-Eisen
Abstract
Wave profiles in Armco iron were obtained with conventional planar impact technique. The free surface velocity was measured using a VISAR interferometric system. Maximum strain rates were determined from the plastic part of the wave profiles to prove the epsilon p = a omikron high 4 relation. The strain rates exceeded 10 high 5 s high minus 1. Numerical simulations of the planar impact tests assuming omikron sub visc about Delta sigma high 2 (according to Swegle and Grady) predicted the steady wave profiles correctly.
