Conclusion
The calculations indicate that the effect of transverse sensitivity on the accuracy of computed principal strains is only marginal. It does not mean that transverse sensitivity in strain gages is not important. It is, and will remain, one of the important considerations in gage design. However, it seems to the users of strain gages, this problem has been successfully solved by the manufacturer.
