biaxial {bs} | R Documentation |
Several data sets related to the BSD are available in the bs package, which have been taken from the literature on this topic.
data(biaxial)
A vector containing 46 observations.
Rieck and Nedelman (1991) reported a data set from Brown and Miller (1978). These data represent results of fatigue tests on 1% Cr-Mo-V steel. Cylindrical specimens were subjected to combined torsional and axial loads over constant-amplitude cycles until failure.
