Generation of a sharp density increase in radiation transport between high-Z and low-Z plasmas
Abstract A sharp density increase (referred to as density incrustation) of the Au plasmas in the radiative cooling process of high-Z Au plasmas confined by low-Z CH plasmas is found through the radiative hydrodynamic simulations. The temperature of...

Creep modelling of 316H stainless steel over a wide range of stress
Abstract Investigation of material creep behaviour in the diffusion controlled creep regime is often unfeasible because of the long duration associated with low stress levels. On the other side, extrapolation from higher creep rates usually provides ...
