چکیده انگلیسی
A critical distance method for predicting the fatigue limit stresses of notched specimens was implemented for notched specimens with a wide range of notch dimensions. Circumferentially notched cylindrical specimens (kt=1.97-4.07) taken from Ti-6Al-4V forged plate were cycled to failure (R=0.1 and 0.5) using a step loading method for estimating the 106 cycle fatigue limit stresses. These experimental data were used in combination with finite element solutions for all specimen geometries to determine a 'critical distance', a quantity or parameter determined from the stress distribution surrounding the notch in combination with fatigue limit stress data from unnotched specimens. A unique parameter was not found for all of the specimen geometries. However, predictions for the fatigue limit stresses of the larger notch geometries may be made with some amount of accuracy using a single value of the critical distance parameter, while reasonable predictions for the specimens with the smallest notch dimensions may be made upon the recognition of an apparent size effect.
