04.1 - Material Issues, Fatigue and Damage ToleranceMODEL CURVES: A SIMPLE WAY TO ACCOUNT FOR COMPLEX EFFECTSA. Bautin¹, Y. Svirsky¹, V. Basov¹, Y. Melnikov¹; ¹1Central Aerohydrodynamic Institute (TsAGI), Russia The approach is to improve the fatigue life estimates and in the same time to reduce the requirements to the experimental data volume based on fatigue life model parameters obtained from tests under typical loading of the structure under consideration. The verification is based on local stress-strain approach and PCM fatigue data. |
