Because distribution of strain, strain rate and temperature in cutting layer is no uniform, so it is extremely difficult to describe materials in cutting process.
Johnson-Cook model describes plastic deformation behavior of materials under high strain rate state only, which is mainly used to describe the material property in the condition of high strain rate, large deformation and high temperature [6].
Therefore, in order to obtain effective and accurate materials, the getting stress - strain curve and developing efficient and accurate experimental setup are very important [3].

The Mechanism Investigation on Propagation and Coalescence Pattern of Three Internal Plane Flaws in Brittle Materials Yanshuang Guo1 , Weishen Zhu1, a , R.H.C Wong 2 ,Shucai Li1 and Chunjin Lin1 1 Geotechnical & Structural Engineering Research Centre, Shandong University, China 2Department of Civil and Structural Engineering, The Hong Kong Polytechnic University, Hong Kong a Zhuw@sdu.edu.cn Keywords: pre-existing flaw; coalescence; wrapping crack; fracture mechanism Abstracts: Under the action of compressive load, the growth and coalescence containing flaws in brittle materials (rock and rocklike materials e.g.) will result in the local buckling and global fracture of rockmass.
It is a typical mechanism of fracture in brittle rocks and heterogeneous brittle materials under uniaxial compression consists in propagation of pre-existing flaws and interaction of wing cracks.
In 2-D case, the wing cracks propagation from the inclined flaws are studied with different materials by many researchers, such as Horii, Nemat-Nasser, Peng, et al [2].
So the resin after freezing can be taken as rock-like material.

Therefore, studying different failure modes of these materials could be of much use.
Although, studies on crack diagnosis in composite materials are quite scarce compared to isotropic homogenous materials, many researches have been performed in this area in the recent years.
