Keywords: Dynamic recrystallization; dislocation theory; plasticity; hot deformation; statistical thermodynamics.
The energy barrier to ignite grain growth is expressed as a function of the strain energy stored in the material and a statistical entropy contribution due to the degrees of freedom available to a dislocation for annihilation.

2.2 Boundary conditions setting
The boundary conditions of the cube and underside hypothesis is the fixed boundary, and the upper surface of the cube (surface of soil) hypothesis is the free boundary.
2.3 Constitutive model and parameters selecting
1) The constitutive model of soil
Due to the soil materials for granular materials, the stress-strain characteristics is very difficult to use elastic constitutive model to describe, the Mohr-Coulomb constitutive model is used in order to be more realistic.
2) The initial expansion of hole radius determined
In order to avoid the circumferential strain of infinite phenomenon which was caused by the initial radius is zero.
