[207] Evaluation of critical stress required to transfer yield across the grain boundary via combination of nanoindentation and FEM calculation

*Ryo KODAMA1, Kei ETO3, Tsuyoshi MAYAMA2, Sadahiro TSUREKAWA2 (1. Kumamoto University Graduate School of Science and Technology, 2. Kumamoto University Faculty of Advanced Science and Technology, 3. Kumamoto University Graduate School of Science and Technology)

Keywords:ナノインデンテーション、GB pop-in、結晶粒界、有限要素解析

ナノインデンテーション試験によって得られたGB pop-inデータと有限要素法を用いて算出したGB pop-in発生時の圧子下の応力場を組み合わせることによって、より厳密に粒界降伏応力を評価した。
