We will study the effective value of the angle which affect on the bolted joint surface by the experimental research method.
This results provide valid reference for the mechanical structure design which with the bolted joint surface, so as to achieving the purpose of more efficiency during the mechanical structure design.
The determination of the effective envelope angle of bolted joint surface is a necessary step in the stiffness calculation of the surface and mechanical design size, which is also play an important influence factor to the overall property in the mechanical design.
Therefore it is necessary to consider the combination of the surface envelope angle in the mechanical structure design which has joint surface.

In industrial manufacturing, punching and/or stamping is the most common process for cutting electrical steel; however, these processes still affect the deterioration of the magnetic properties of ESs and the high cost of the cutting tools.
Additionally, many research emphasized the detrimental impact of HAZ on magnetic properties by laser cutting of ESs [5, 6, 7].
Minimization of the HAZ along the cut edge should be required in the laser cutting for maintaining the magnetic properties.
Initially, the HAZ was one of the most influential factors affecting the magnetic properties of the electrical steel sheets [14].

It is also known that the structure and properties of the TiNi alloys are sensibly affected by thermal treatments [4] Therefore the presents work has as its objective to investigate the changes in structure and properties of an almost equiatomic TiNi alloy caused by annealing at temperatures in the interval from 300 to 500ºC, followed by air cooling.
These samples were characterized for their transformed structures and changes in properties.

Introduction Currently High P-T(High Pressure and Temperature) rheometer is widely used in the Earth's interior material rheological properties and dynamics research [1].
The curve d shows that the different contact types on the two end surfaces of core mainly affect the axial stress nearby.
The bevel of pusher and pedestal is a key factor to affect the axial stress, by which the axial preload can be enhanced at the inner surface of core.
The end pressure and the angle of bevels are the two key factors affecting the axial stress of core and the two reasons leading to the yield of pusher and pedestal.
