The family of composite materials with fibers which appeared in the 1940s makes profitable the
high mechanical properties of certain fibers.
The quality of this connection influences considerably the mechanical properties of the obtained material.
Through the reinforcement of structures by composite materials, the main goal is to improve the mechanical properties of concrete.
All the mechanical properties are introduced according to the experimental data and the composite grid is taken into account in the behavior model.

The factors affecting tire-pavement noise spectrum were analyzed, such as temperature, speed, age of pavement and so on.
The dense asphalt-rubber pavement was the most widely used in urban road in the last decade, whose nominal maximum aggregate sizes were mainly 13mm or 10mm. [1] However, its noise reducing properties is not well known compared with other asphalt pavement.
Research Institute of Highway Ministry of Transportation was asked to conduct the research. it had studied acoustic properties and mechanical properties of several types of asphalt mixture used in Beijing with the help of advanced test equipment, such as Simple Performance Tester, Universal Testing Machine, Asphalt Pavement Analyzer, Reverberation Room.
The factors affecting tire-pavement noise spectrum were analyzed, such as temperature, speed, age of pavement and so on.
The master curve of dynamic modulus is fitted with Sigamodal function, and the master curve of phase angle is fitted with Gauss curve and adopted the same shift factor as dynamic modulus master curve.

Spring back is not only affected by the tensile strength and stress but also influenced by the thickness of the plate, bending radius and angle.
The spring back issue has been studied over the years to compensate for the undesired shape errors and to identify the influence of main factors, such as material of workpiece, tooling geometry, and process parameters, on the amount of spring back, both experimentally and numerically.
This is caused by the elastic properties of the metal and the strain change that produced by the elastic recovery.

Further, a modified mechanism with higher stiffness and improved process protection system properties will be described and compared to the current status.
The examination of the affected components suggests a mechanical overload, which mainly results due to collisions.
For example the stiffness or the moving masses are influencing factors [7].
This mechanical system operates independently of the used drive types and works energy-self-sufficient.
After the detection the control unit of the machine tool will run an emergency stop to support the mechanical protection system.

The water uptake capability and the weight loss were
measured up to 14 days and their mechanical properties were assessed with compression tests.
The mechanical properties were assessed using compression tests in dry state (Instron 4505).
This can be explained by two possible factors; (i) the formation of a siloxane network which prevented the material to degrade faster and (ii) due to different surface area of the porous structures.
These results may be explained by the change on the size and CS CST1 CST2 CST3 CST4 0 10 20 30 40 50 Weight loss (%) (B) CS CST1 CST2 CST3 CST4 0 200 400 600 800 1000 1200 1400 1600 Water uptake (%) (A) orientation of the pores (see Fig. 1) which affected the final mechanical properties of the porous materials.

Influences of these different dielectrics properties on machining speed, tool wear, surface cracks and roughness were compared.
During the past decades, a wide range of studies has been done on Ti-Al alloys because of their important properties such as fuel economy and good thrust to weight ratio.

Naderi etc. [2] studied the factors of martensite transformation and discussed how temperature and deformation effect the martensite transformation.
C Lei etc. [7] discussed how temperature affected mechanical properties of parts in hot stamping.
Hence, it is hard to analyze the mechanical property of hot-stamped part directly.
In this process cooling rate is the major factor that has impact on martensite transformation.
Hot-stamping is a complex thermal-mechanical coupled process.

Material properties of the weld zones
were determined by minitensile specimens.
The presented research activity tries to give basic knowledge on the crack behaviour in an idealized weldment under various load cases. 2 Material Properties of the Weld For a complex analysis of the weld mechanical properties of all its parts need to be known.
Along with the known hardness measurements a complete set of mechanical properties of an electron beam welded joint of bronze and steel was obtained.
With heterogeneous materials stress intensity factors cannot be determined with usual formulas.
The properties of the HAZ have partially different properties from the base materials.
