And eventually it gets close to the material yield point with material deformation growing and more homogeneous.Shearing section level comes between the late stage of plastic deformation and the initial stage of the shearing, which is the best period of shearing.
Materials reaches the maximum degree of deformation with shear force decreasing from the maximum value.

Experiments
Experimental Materials.
When the steel melted totally, the calcium or magnesium powders sintered body was added into the molten steel though the material feeder.
As experimental materials had highly active materials in the test, the argon was used to cut off the air to make sure that the experiment went smoothly.

Key words: Senior apartment; psychology; living requirement; architecture design.
The space for body exercise needs to cover soft-material floors which prevent some accident including falling, sliding and so on.
The constructions from neighborhood materials tailor measures to suit local conditions, which made them different from areas to areas.

The FS technology of a con-rod uses the notch quasi-brittle of the material to change the stress state, which makes the material yield strength in designated region higher than the brittle fracture strength required [3].
The material used was C70S6 steel.
