Abstract
For the percolation model of strain in a deforming metal proposed earlier, we develop a sum rule and mean field approximation which predict a critical point. The numerical work is restricted to the simpler of two cases proposed in the earlier work, in which the cell walls are strong, and unzipping of the dislocation entities which lock the walls into the lattice is not permitted. For this case, we find that strain percolation is a new form of correlated percolation, but that strain percolation is in the same universality class as standard percolation.Citation
