Effect distribution of residual stresses on three different materials physical properties of hardness are analyzed by using the finite element model during the process of high speed cutting.
The results show that metal material hardness is the key factors to residual stress.
Tensile residual stresses on the surface of components dangerously affect the life of them in operating conditions [4-6].
Consequently the plastic deformation will be affected.
In this paper, a finite element model was built to analyzed effect of material physical properties on magnitude and distribution of residual stresses.

This condition is measured by mechanical properties such
as yield strength, tensile strength, fatigue strength and hardness.
In this study fatigue properties are particularly investigated in detail.
Table 1 lists the mechanical properties of the test materials.
The annealing process followed by the tempering process performed on Material Q did not effectively reduce the brittleness in the microstructures, affecting the tensile and fatigue performance.
Conclusions (1) Not one of the tested materials is ideal as they do not comprise the highest values of the three mechanical properties combination which are tensile strength, fatigue limit and hardness

Introduction
The existence of joint dramatically affects physical and mechanical properties of rock mass.
Shuangjian Niu [3] studies rock mass strength by numerical method and thinks that peak strength is controlled by joint geometric parameters, but that residual strength is controlled by mechanical properties of joint face.
So, it can be regarded that the sensitivity of the factors affecting the jointed sample’s strength falls in the order: joint dip angle, joint strength and rock block strength
Numerical investigation on the sensitivity of jointed rock mass to various factors [J].
Uniaxial compression experimental research on deformation and failure properties of brittle marble specimen with pre-existing fissures [J].
