Abstract: | The plastic zone at a crack tip in a finite anisotropic body is studied. A boundary-value problem is formulated in terms of
the components of the covariant displacement vector for small strains. Particular attention is given to the case of plain
strain. In this case, a numerical solution is found for a long rectangular body with a central crack under tension. As a result,
conditions for the occurrence and development of a plastic zone at the crack tip are established. A plastic zone on the lateral
surface of the body is discovered. How both zones extend and coalesce is elucidated. The effect of anisotropy on the occurrence
of a plastic zone is evaluated
