In the above-mentioned paper an extraneous factor of 4 was introduced into equation (1). This equation should read

This corrected equation has the important feature that the microstress is isotropic for an elastically isotropic material, for which s₄₄ = 2(s₁₁–s₁₂).

Use of the erroneous equation given in the paper has resulted in significant errors in figure 11 and in values derived from that figure that were reported in table 3. Other errors in the stress calculation have also been corrected. A revised figure and table are given below.
