Test Data

(1) Table F.3.1 gives values of mo for selected details in certain wrought alloy products which have been derived from test data.

(2) For R-ratios between R = -1 and R = 0 a linear interpolation of inverse mo value may be used.

(3) The R-value may be based on the applied stresses only without taking into account residual stresses.
