D03 線形破壊力学と有限要素法を用いた応力拡大係数の計算(宇宙構造)

抄録

This report describes some numerical analysis by finite element method with quarter-point element. To obtain the stress intensity factor which is important physical parameter to show the stress singularity near the crack tip, by the finite element method, some finite element formulations exist. In this report, we use the quarter-point element.
