Abstract |
The effect of steel grade on reversals to crack initiation in notched specimens 2N sub i essentially reflected differences in tensile strength. The higher strength grades (B80RK,RQC100) required a greater value of the notch parameter K sub f delta S for a given 2N Sub i than the lower strength grades (1020,A36,B40P0). Stress ratio R had a significant effect on 2N Sub i with 2N sub i increasing as R decreased from 0 to -1. The various predictive models studied (local strain, nominal stress, empirical) gave similar results in terms of the variability in estimates of 2N Sub i and the relation between the predicted and observed values. |
