In particular, the use of carbon nanofillers into the matrix of construction materials can provide enhanced properties to the material in both of mechanical and electrical performance.
Appropriate nanosized additives can be inserted into structural reinforced concrete (RC) as fillers, providing enhanced chemical, physical, mechanical and electrical properties.
Among available fillers, carbon-based ones appear particularly suitable, due to their enhanced mechanical and electrical properties.
They possess remarkable mechanical and electrical properties which make them suitable to cast smart composites for constructions.
Those particles were chosen for their enhanced mechanical and electrical properties which make them possible candidates for the realization of smart sensors for the monitoring of structures.

Power performance is good or bad directly affects the effect of automobile driving on the highway.
In theory the automobile maximum climbing angle is greater than the actual value because that in actual case as uphill the car will be subjected to the impact of factors such as the wind resistance, the soft or rough surface resistance.
(8) The is the automobile rotate quality conversion factor; is the quality of the automobile; is the driving acceleration.

A check for interface failure based on the adhesive, GD414, property is done to investigate the failure behavior, also to gain a simplified interface treatment.
The results show that gaps can release the stress of the interfaces while it can’t affect the whole stress distribution too much.
Besides, to confirm the failure criterion, the paper makes an assumption that if 50% of the specific path fails, then the path fails to affect.
The whole nozzle is at a high safety factor.

Simulation Analysis of factors shaping the auto crash in the manufacturing process is the introduction of crash simulation models (mainly refers to the stamping process) affect the material properties of the crash simulation analysis techniques.
Domestic scholars studied the typical stamping parts forming factors impact the results of the crash, but the results of these studies illustrate the effect of directly forming factors stampings case of vehicle crash [6].
Stamping direction selection is reasonable, directly affects the quality and complexity of the mold structure stampings.

After learning about the law of bolt-end connection-function influenced by parameters of bolt-end structure, how to analyze influence each factor to the bolt mechanical property and to find out the optimal bolt-end structure is main research content.
It is an experiment about three factors and three levels.
As for indentation depth, according to range, it is easy to know that both connection strength and elongation are important factors, and A2 is better, so the reasonable indentation depth is 1.5mm.
At the same time, compared with other factors, B is the second cause and both B1 and B2 are same for different connection strength.B2 is the appropriate.
When it comes to range, all C factors are non-essential, so C2 is good at saving cost and its yield strength is 235MPa.

Plastics reinforced with fibers show the dependence of mechanical characteristics on linear dimensions - the scale factor [11-13], moreover, the significant influence of the technology of manufacturing and preparing a specimen on its mechanical characteristics is observed [14-17].
This phenomenon has been simulated by setting the degradation coefficient of material properties.

To acquire a balanced high temperature mechanical and oxidation properties, these materials generally have multiphase and multicomponent structures.
Microstructural properties such as volume fraction, distribution and shape of the component phases can also affect the oxidation behavior of these materials [5].
However, the effect of 25 at.% Cr on the other properties of the composite material was not clear.
Oxidation and the mechanical properties of this new group of composites have been improved during the last two decades.
Since the model assumes that oxidation is controlled by the dissolution and diffusion of oxygen in the liquid phase, the rate oxidation loss of the borides is controlled by the factors including the amount of the liquid boron oxide present in the scale, its viscosity and properties of the oxide of the metallic component.
