TLDR
Results of systematic molecular-dynamics computations of the elastic properties of single-crystalline tungsten containing structural defects, voids and over-pressurized He nanobubbles related to plasma exposure of tung sten serving as a plasma-facing component (PFC) in nuclear fusion devices contribute directly to the development of a structure-properties database that is required for the predictive modeling of the dynamical response of PFCs innuclear fusion devices.
