Abstrakt: Solid state experiments at extreme pressures (0.1 – 1 Mbar) and strain rates (106–108 s-1) are being developed on high-energy laser facilities. The goal is a capability to test constitutive models for high-pressure, solid-state strength of materials. Relevant constitutive models are discussed, and our progress in developing a ramped-pressure, shockless drive is given. Designs to test the constitutive models with experiments measuring perturbation growth due to the Rayleigh-Taylor instability -in solid-state samples are presented. Results from dynamic diffraction and EXAFS lattice diagnostics are given, showing that compression, phase, and temperature can be inferred on sub-nsec time scales. © 2006 American Institute of Physics [ABSTRACT FROM AUTHOR]
