Possibility of a life-time extension for wwer-1000 reactor pressure vessels beyond the design period
Trudy Odesskogo Politehničeskogo Universiteta, 2020 At present a life-time extension for WWER-1000 reactor pressure vessels is an actual issue in Ukraine. For a decision about the life-time extension it is needed to assess mechanical properties and the critical brittleness temperature TK for the RPV ...

Brittle yielding in supercooled liquids below the critical temperature of mode coupling theory
The Journal of Chemical Physics, 2022 Molecular dynamics computer simulations of a polydisperse soft-sphere model under shear are presented. The starting point for these simulations are deeply supercooled samples far below the critical temperature, Tc, of mode coupling theory. These samples are fully equilibrated with the aid of the swap Monte Carlo technique.
