3537 完全溶込み十字溶接継手のFLARPによる疲労寿命解析(S14-4 FLARPによる疲労き裂発生伝播シミュレーション(4),S14 FLARPによる疲労き裂発生伝播シミュレーション)
詳細
Fatigue crack initiation and propagation analysis by "FLARP" developed by Toyosada has been applied to the fatigue test results of cruciform-welded joint with K-butt welds of 355 N/mm^2 class steel. As input data for FLARP analysis, the relation of stress intensity factors to crack depths was calculated by using influence coefficients for a semi-elliptical surface crack in flat plate by Shiratori and stress distribution calculated by FE analysis in the section including weld toe from which a crack occurred.
