2. There exists a condition of compatibility among the neighboring grains during the deformation of polycrystals; that is, if the development of voids or cracks is not permitted, the deformation in each grain must be accommodated by its neighbors.

• This accommodation is realized by multiple slip in the vicinity of the boundaries which leads to a high strain hardening rate.

• It can be shown, following von Mises, that for each grain to stay in contiguity with others during deformation, there must be operating at least five independent slip systems - Taylors Theorem.
