Hydrodynamics Calculations for MINI JADE Gages.
Abstract
Two-dimensional hydrodynamics calculations were made with the STEALTH code to determine the response under 10 GPa loading of three designs of the SAI particle velocity gage. The calculations showed which design best measured the free field particle velocity. Two-dimensional calculations were also made for four designs of the SRI cylindrical stress gage. The calculations determined that the internal gage dynamics, particularly shock reflections, were primarily responsible for differences between the gage response and the free field stress. A material parameter study using a one-dimensional model was made to see if the use of other material combinations would improve the gage response. The internal dynamics of the flat pack stress gage were investigated using a one-dimensional model. The calculations indicated the severe early-time Ringing seen in the gage response is caused by oscillatory motion of the iron plates.
