Polycrystalline diamond (PCD), is a tool material and widely used in nonferrous metal processing due to its excellent properties, such as high hardness, high wear resistance, high thermal conductivity and low friction coefficient.
Wang yongsheng et al. [7] established the finite element model of orthogonal cutting in deform-3D software, and considered the key factors affecting cutting simulation, such as the constitutive relation of workpiece material, automatic repartition of local grid, chip friction and chip separation, and obtained the qualitative relation between cutting speed and residual stress.
Therefore, it is the key to ensure the accuracy of the finite element model to build a constitutive model that can truly reflect the characteristics of the material processed by comprehensively considering the influence of various factors on the material flow stress.
In addition, with the increase in feed, milling cutter and chip contact length increase, increase the area of cutting heat, chip take away more heat, several factors affect each other, so that the temperature increases.

The most important technical innovation is using of the corrugated webs substituting for flat webs, so the corrugation configurations have great influence on the mechanical property.
From the formulas above and theory analysis, the factors of hw, tw, hr, b and d have an appreciable impact on the shear capacity.
The factors of hr, b, and d are the targets of optimization.
At the same time, GJ13 showed up excellently plastic properties.
Conclusions On the basis of the mechanical property analysis of H-beams with corrugated webs, an optimization research on the corrugation configuration is conducted.

Introduction Laminated composites possess superior mechanical properties, such as high specific strength and stiffness, corrosion resistance, and better fatigue properties in comparison with metallic solutions, which makes them good candidates for long-term structural applications [1].
The current method is to take photographs of the crack propagation processing continuously, then use the artificial method to measure the crack extension length, which is influenced by human factors, and has low precision, low efficiency.
The global threshold is simple, without affecting the image brightness and contrast characteristics [13].
From Fig. 3, it can be seen that the image has some defects, and some places are less connected, which will affect the following operation.

Introduction When external stress is applied on a ferromagnetic material, its magnetic properties will be altered.
Some of the magnetic properties of ferromagnet such as magnetic hysteresis, Barkhausen effect and magneto elastic energy has been widely studied.
Results of fatigue load test The magnetic testing in fatigue test of the steel sample was performed with deferent experimental factors.
The local stress concentration is not the only reason for magnetic abnormality on local position, the local micro structure and stress concentration and other local abnormal factors should also be considered.

When three welding conditions, including welding configuration, welding speed and laser power, are sequentially altered, supersaturation of liquid aluminum is numerically analyzed to optimize the growth kinetics of dendrite tip with decease of thermo-metallurgical factors for solidification cracking to salvage the weld properties during promising laser welding repair of multicomponent nickel-based single-crystal superalloy.
The material properties of nickel-based superalloy are available in the literature.
The thermo-metallurgical factors morphologically mitigate centerline cracking susceptibility through microstructure refinement to spontaneously salvage single-crystal dendrite growth.
In other words, the consistency among these metallurgical factors nonaxisymmetrically augments microstructure inhomogeneity.

In the open-die forging simulation，heat transfer coefficient between blank(880℃) and open-die (200℃)is 11, the surrounding environment temperature is 20℃, friction factor is 0.3.
Therefore, flash parameter is an important factor which influences on metal filling, forging force and flash materials consumption.
Added value does not affect the equipment tonnage selection, larger bridge width leads to Smaller loss of metal flash, higher material utilization and life of mould bridge width, we suggest adjusting the bridge width for 11 mm in the mould design.
Closed-die forging Closed die forging blank is formed in the complete closed mould cavity, therefore solid metal flow properties is considered, namely, whether the solid metal under pressure can realize volume redistribution, and fill the mould cavity.
