The KOMPSAT-5 is the first synthetic aperture radar satellite of South Korea, and its mission orbit is 550km sunsynchronous(More)
In this paper, a self-consistent plasticity theory is proposed to model the mechanical behaviours of irradiated face-centred cubic nanocrystalline metals. At the grain level, a tensorial crystal model with both irradiation and grain size effects is applied for the grain interior (GI), whereas both grain boundary (GB) sliding with irradiation effect and GB(More)
