This is a summary of the constant-load, constant-temperature mechanical creep data that has been collected on PBX 9502 in tension and compression over the last 5+ years. This work was primarily funded by the Enhanced Surveillance Campaign (C-8).
This report briefly summarizes an interesting set of experiments performed on PBX9501 in FY13. It also describes the use of the experimental data in a constitutive model development program. The experiments were requested as a follow-on to a set of cyclic compression experiments performed by Darla Thompson in 2008. Thompson originally performed the experiments to demonstrate a capability and to stimulate discussions on what experimental data W13 needed. Those experiments proved crucial in demonstrating that the material exhibited permanent deformation after removal of load, viscoelastic recovery, and some form of damage. Further experiments were requested to flesh out a viscoelastic-viscoplastic-viscodamage model.
