The lattice strain

SpletAbstract: Volumetric strain can be divided into two parts: strain due to bond distance change and strain due to vacancy sources and sinks. In this paper, efforts are focused on studying the atomic lattice strain due to a vacancy in an FCC metal lattice with molecular dynamics simulation (MDS). The result has been compared with that from a continuum Splet16. jan. 2024 · Lattice strain in irradiated materials unveils a prevalent defect evolution mechanism Aurélien Debelle, Jean-Paul Crocombette, Alexandre Boulle, Alain Chartier, Thomas Jourdan, Stéphanie Pellegrino, Diana Bachiller-Perea, Denise Carpentier, Jayanth Channagiri, Tien-Hien Nguyen, Frédérico Garrido, and Lionel Thomé
