3534 ΔK_<RP>規準による変動振幅荷重下での疲労き裂伝播シミュレーション(S14-3 FLARPによる疲労き裂発生伝播シミュレーション(3),S14 FLARPによる疲労き裂発生伝播シミュレーション)
詳細
A new crack opening/closing simulation method is developed utilizing the crack tip stress field parameters evaluated by FEM. By combining this method and the CP-System, the growth behavior of fatigue cracks can be computed for large-scale structures under variable amplitude loading. In order to demonstrate the usefulness of the developed program, fatigue crack propagation in a ship structure is computed under realistic wave load sequence.
