The derivation of material properties from measurements of radiation induced stress-time histories

PDF Version Also Available for Download.

Description

Material response experiments using the SATURN soft x-ray source in conjunction with hydrocode modelling have been used to determine equation-of-state parameters for aluminum. In these experiments, stresswaves in irradiated targets have been measured using both quartz and PVDF piezoelectric stress gauges for a wide range of incident fluences. The induced stress profiles are sensitive functions of. (1) the deposition profiles in the target material, (2) the temporal history of the radiation source, and (3) the target material-properties. Analysis of the experimental data has shown that observed changes in the shape of the induced stresswave as fluence is varied can be ... continued below

Description

Material response experiments using the SATURN soft x-ray source in conjunction with hydrocode modelling have been used to determine equation-of-state parameters for aluminum. In these experiments, stresswaves in irradiated targets have been measured using both quartz and PVDF piezoelectric stress gauges for a wide range of incident fluences. The induced stress profiles are sensitive functions of. (1) the deposition profiles in the target material, (2) the temporal history of the radiation source, and (3) the target material-properties. Analysis of the experimental data has shown that observed changes in the shape of the induced stresswave as fluence is varied can be directly correlated to phase transitions. The unique combination of x-ray energy and irradiation time allow phenomena important for determining equation-of-state parameters to be studied separately. By temporally separating the development of thermomechanically induced stress from stress induced by material vaporization a very sensitive measurement of vaporization energy is possible.
