The strength of diamond is critical for both static and dynamic high-pressure research. Under the compression of shock waves in the range of hundreds of gigapascals, single-crystal diamond exhibits strong time-dependent inelastic deformation, making it a crucial issue for the development of an accurate material description of diamond capsules used in inertial confinement fusion (ICF). Here, we propose a dual-media material model for achieving a new ICF alternative substance, where the main mediu
