摘要
Tungsten is one of the promising candidates for the divertor plate in International Thermonuclear ExperimentalReactor (ITER) because of its high melting temperature, high thermal conductivity and low sputtering erosion.During the operation of ITER, it will be exposed to high energy particles: hydrogen, helium and neutron, producinghigh density of interstitials and vacancies which will change the structure and properties of materials. The formationof defects changes the local stress/strain field, and the external stress/strain field will also affect the properties ofdefects. In this work, we use the Large-scale Atomic/Molecular Massively Parallel Simulator LAMMPS[1] to studythe formation of defects under strain field in tungsten.
