Dynamic characteristics of high quality steel in Johnson-Cook's model for fast processes simulation in CAE programs

摘要

The paper presents the dynamic behavior of gain for higher quality steel (armor) for the numerical simulation of fast processes, implemented in programs CAE, determined on the basis of results obtained from tensile tests of round samples conducted on the MTS testing machine type and rotary hammer, in terms of strain rate from 0,0001 to 500 s~(-1) in tabular and equation JC. Posted simulation results armor penetration high quality steel bullet caliber 12,7 mm compared with experimental results.
