Abstract
On the basis of a result obtained by DE WIT and KOEHLER an exact formula has been derived for the critical shear stress of a Frank‐Read source, which can be applied to anisotropic crystals as well. Application of this formula in a few numerical cases shows that the effect of the anisotropy can be neglected for face‐centred cubic crystals, but has to be taken into account for hexagonal crystals such as graphite.
