[3H05] Study on Effects of Solute Atom Clusters on Stress Intensity Factor at A Crack Tip Studied by Discrete Dislocation Dynamics

Tomohisa Kumagai1, *Akiyoshi Nomoto1, Akiyuki Takahashi2, Hayato Sugasawa2 (1. Central Research Institute of Electric Power Industry, 2. Tokyo University of Science)

Keywords:Irradiation embrittlment, Discrete dislocation dynamics, Stress intensity factor, Solute atom cluster

照射等によって形成される溶質原子クラスターを念頭に、これらの欠陥が亀裂先端の応力拡大係数に及ぼす影響について離散転位動力学法を用いて検討した。
