The assumptions of FE model are as following: (1) the distribution of current is uniform on the cross section of solenoid; (2) the conductivity and magnetic permeability of materials are constant and isotropic; (3) free of the vortex; (4) the temperature dependence of material property is ignored.
Due to the compressive force, the deformation of specimen will be restricted in the axial direction, and only circumferential distortion will occur, so it can be thought as the state of uniaxial tensile stress which is commonly used to research the material dynamic properties and fracture process for ductile metal materials.

The properties of materials are represented as the equation below
The datas of chip thickness are treated by non-linear fitting method,we will find that the chip thickness is in the same the trend of feed, when the feed increases, cutting energy increasing, and that will lead to the increase of cutting temperature, and accordingly the plastic of materials increases, so cutting thickness increases.

The modelling of metal bioactive sites, metalloenzyme reaction centres, nonlinear optical materials, homogeneous or heterogeneous catalysts for several reactions, and luminous materials all make use of a number of the Schiff base ligands and metal complexes [4,5].
Due to its distinctive structural characteristics and wide range of applications, including catalysis, optics, and luminous materials, cuprous chemistry has attracted particular interest.
These applications include biological sensors, fascinating physical properties, and luminescent materials[6].
FT-IR Spectroscopy The analytical method known as Fourier Transform-Infrared Spectroscopy (FT-IR) is used to distinguish between organic and, in some situations, inorganic materials.

The material properties in the finite element model are also borrowed from the three papers mentioned above and are shown in table 2.
We also found that the material properties have an important effect on the buckle propagation pressure.
