In the field of manufacturing through cutting by material removal and more especially when manufacturing on NC machine tools, there is a clear need to develop a tool capable of accurately simulating the machining stage.
But it does not allow problems of collision, unsuitable cutting conditions, high speed displacement in the material, etc. to be managed.

The macroscopic non-uniform sample was obtained by putting silt clay block into sand sample, evolution of shear band during the loading process showed that the discontinuation of stiffness formed at interface of two materials, with inhomogeneous deformation developing, macroscopic continues shear band fully formed.
In paper of Nemat-nasser and Okada, shear localization in granular materials had been studied radiographically and microscopically, the deformation of the shear band zone was quantified[5].
