From the Figure 2(c), the material below the tool is forced under rake face with great hydrostatic pressure.
The volume of chips is not the same as material removed compared with that of initial material.
Since great hydrostatic pressure is forced on the deformed materials, the perfect FCC lattice structure changes into a compact structure.
The material in the finished surface undergoes elastic and plastic recovery.

In addition, in order to convenient mathematical treatment, the traditional methods adopt the form of the third strength theory in the simple but be safe to get equivalent stress, and assuming the same cylinder material in each layer.
The methods and procedures when handing stresses such as the use of complex issues that multi-cylinder, cylinder layers of different materials or different allowable, and does not increase the difficulty.
Therefore, in accordance with the principle of equal strength, the equivalent stress value of σe1, σe2, σe3 of the wall in the inner cylinder, middle cylinder and outer cylinder should be all equal to allowable stress [σ], so that makes the stress distribution of combination cylinder tend to be more uniform, each part of the materials can be used most effectively.

Fig. 1: Various configurations of a chevron-notched test specimens, adopted from [3] Introduction Destructive tests of specimens from quasi-brittle materials subjected to three-point bending (3PB [1]) are very common way of testing of various building structures (and its parts).
Later applications on rock materials made it to be suitable instrument for evaluation of fracture toughness KIC [5,6] – the International Society for Rock Mechanics (ISRM) has proposed it to be suggested as method for testing rock’s fracture toughness [7,8,9].

Introduction Nowadays magnesium alloys become the most developing potentially material due to theirs low density, high specific strength, good shock absorption ability and excellent cutting performance, which is widely applied in aeronautic, automobile, electronics and communications industries[1,2].
While subsequent thermal treatment can further enhance mechanical properties to satisfy the needs of structural materials.
Material and experimental The experimental samples were taken from as-cast AZ80 magnesium alloy billets.

Introduction With the heat from the reaction between the metal oxides and aluminum powder being the heat source,SHS welding technology fabricates the fusion welding joint with certain shape and size utilizing reduced molten metal flowing out to directly or indirectly heat the workpiece.Compared with traditional welding technology,the SHS welding technology possesses following features[1]: (1)it can utilize reaction's raw materials to synthesize gradient material to weld different types of material,in order to overcome the incompatibility of the chemical,mechanical and physical properties between different base metals;(2)strengthening phase such as strengthening particles, short fiber,crystal whisker and so on can be added into the welding powder to increase the number of materials available to be welded and intensify the hardness of the welding joint;(3)it generates certain amount of energy which can be used in the weld,saving energy in one word;(4)in so far as the weld of some certain
Experimental materials and methods The experiment's base metal is steel Q235,while the welding powder contains 11% of the aluminum powder(200 mesh),55% of the metal oxides containing 88% of the copper oxide and 2% of the slag forming constituent.When welding,igniting the igniting agent will cause the SHS reaction to happen automatically thus welding the workpiece as well.In essence,this reaction is a redox reaction of aluminum and copper oxide,and the reaction equation is as follows: 2Al+3CuO=Al2O3+3Cu+1519KJ/mol  (1) The adiabatic combustion temperature of the reaction above is 5151K,which in theory is adequate to melt the steel components[2].As the base of the welding metal,copper can be obtained in the reaction,stuffed in the welding seam between the base metals and satisfied the requirement of welding base metal.
